Foreword
Kupu takamua
Protecting our streams, rivers, lakes and harbours is a top priority for Aucklanders,
and there are big challenges we need to tackle.
We’ve made a good start on some of the immediate issues, like cleaning up our
beaches and replanting our streams. However, there is much more we need to do if
we are to secure our water future.
We want to agree a vision for our waters, and identify the investments we need
to make to achieve that vision.
It is all too easy to take water for granted. After all, getting clean, reliable
drinking water is as easy as turning on a tap, and we can safely swim, fish or kayak
in most places, most of the time. We rely on experts to manage the details for us.
But perhaps that leads us to undervalue what we have.
Events around the world, from California mudslides to Capetown droughts, remind
us how fragile our water systems are. Too much water, or too little, can be disastrous.
The deluge of plastics and other pollutants in our oceans drives home how much
damage we are doing to our waters and ultimately to our own future.
In Auckland, localised floods, slips and coastal erosion happen often. Although
it rains frequently, we have to rely on our neighbours in the Waikato to meet our
drinking water needs. As our population grows, and the impacts of climate change
begin to bite, we need to think very carefully about our water future.
Working in partnership with Māori is an essential part of this process. Te mauri
o te wai, recognising the lifegiving nature of water, is a view that treats water
with the respect it deserves. With water at the centre of our decisions, it is my
hope that we can begin to build a healthier, more resilient Auckland.
We can all contribute to a better water future. I invite you to read this discussion
document and let us know what you think. Let’s work together to ensure a secure,
sustainable and healthy future for water in Auckland.

Water and Tāmaki Makaurau / Auckland: inseparable
stories
Te wai me Tāmaki Makaurau: ōna pakiwaitara motuhake
Water, or wai, is a precious taonga, a treasured resource. It gives us life,
shapes our environment and adds to the beauty of our region.
Our connection with water
Our connection with water is part of what makes living in Tāmaki Makaurau / Auckland
so special.
Historically, our harbours and streams were abundant sources of kai / food for
mana whenua and manuhiri / visitors alike. They also formed important transport
and trade routes.
Waka, ships, ferries and freighters brought trade and economic prosperity. This
allowed us to grow into a city of 1.66 million people with more than a third of
Aotearoa / New Zealand's economic activity.
The decline in water quality
As the population grew, we built water infrastructure to keep us healthy and
safe - but we didn't always look after the waters that sustained us. Rivers were
piped, wetlands were drained, and plumes of sediment and other pollutants were discharged
into the harbours.
In both urban and rural areas, water quality has declined. Freshwater and marine
environments are showing the stress of decades of pressure.
As the population grows and the impacts of climate change take effect, these
stresses will become more severe. Our water infrastructure - the networks that manage
our drinking water, wastewater and stormwater - also faces new pressures.
Clean, healthy water is essential to our future.
The region is 75 per cent water. As we continue to grow and change, we need to
look after this most precious taonga.

A conversation we need to have: The purpose of this
discussion document
He kōrero me tutuki i a tātou: Te take mō tēnei pūrongo whakawhiti
kōrero
Defining our water future is a task for everyone together. We know that we will
face some big water challenges in coming years. What kind of water future do we
want to create? What vision could we aspire to, and what are the big issues we need
to tackle?
Problems with water concern us all
We've talked a lot about water lately. Aucklanders have very clearly told us
that clean and healthy water is a top priority. Safeswim has raised awareness about
the health risks we face when our infrastructure doesn't work as well as we would
like.
Storms, flooding and coastal inundation have made clear the challenges of living
in an ever-changing water landscape. This is especially real for the communities
that have been directly affected. Community restoration programmes have revealed
strong personal connections to our natural ecosystems.
Developing a Water Strategy
In June 2018, we decided to prepare a Water Strategy for Auckland to ensure that
our actions respond to the challenges and opportunities we have to improve water
outcomes.
This discussion document is a first step in the strategy's development. It looks
across the full range of water issues, and begins to identify the choices that we,
as Aucklanders, will need to make in coming years.
We all need to understand the issues, so that we can set some regional directions
for how we:
- take care of natural waterbodies
- meet our daily water needs as our population grows
- look after our waters while managing our growth and development
- prepare for changes in our climate and our communities.
Our challenges
We face some big challenges that will shape what we can do:
- Our waters are degraded, especially where they are close to urban areas.
We need to clean up our rivers, lakes, streams and harbours.
- Freshwater is a scarce resource, even though it rains frequently. We have
limited large rivers, lakes and groundwater resources in the region to draw
water from, and we are becoming increasingly reliant on the Waikato region to
meet our needs. We are going to need to make better use of the water that we
have, or agree to develop new sources of supply by 2050.
- We live in an ever-changing environment, vulnerable to natural hazards such
as flooding, coastal inundation, erosion, drought and the effects of climate
change. We will need to make changes to be ready for the increasing risks.
- Responding to water issues takes money and time (and the costs of doing
nothing will likely end up being higher in the long run). We want to make sure
our decisions are improving our water future, not deferring the problems for
future generations to resolve.
Decisions we have to make
In coming years, we will have to make big, potentially controversial decisions
about how we manage water. We know that people have different perspectives on water
issues. We also know that you are more likely to support decisions that you were
involved in shaping.
To help us, as a starting point in this process, we want to sketch out a broad
framework that we can agree to. After setting out the local and national context,
this discussion paper steps through a proposed framework for how we think and make
decisions about water in Tāmaki Makaurau / Auckland (see The
proposed framework for an Auckland Water Strategy).
A framework for water decisions
The proposed framework contains:
- an aspirational vision for our water future
- five values that describe the reasons we attach importance to water
- four big issues that are at the core of our water challenge
- six principles that will guide our actions as we move forward
- four processes that we need to work on, to support quality decisions.
We want you to have your say
We want to hear what you think. With your feedback on this proposed framework,
we'll be able to develop an Auckland Water Strategy that moves us toward an agreed
water future.
- Do the vision and values reflect what matters to you?
- Have we accurately described the ‘big issues’?
- Do you think the principles and processes will help us make progress towards
the vision?
We have taken advice from the Mana Whenua Kaitiaki Forum to prepare
this discussion document. They have said that te mauri o te wai
should be at the centre of the strategy, with rivers, estuaries and
harbours restored to a state of health (see A vision
that speaks to this place).
Involving mana whenua in governance and decision-making roles is
an ongoing part of this process, as well as making sure they are able
to actively exercise kaitiakitanga in practical ways.

The proposed framework for an Auckland Water Strategy
Te pou tarāwaho o te Rautaki Wai mō Tāmaki Makaurau e whakaarotia
nei
Infographic text description
This infographic sets out the proposed framework for the water strategy. The
Auckland Plan is the overarching plan, with three key challenges: population growth,
environmental degradation and shared prosperity. It sets six outcomes: belonging
and participation, Māori identity and wellbeing, homes and places, transport and
access, environment and cultural heritage, and opportunity and prosperity.
Underneath the Auckland Plan, the proposed framework for the water strategy is
presented in a table. The first line is a header: Te Mauri o te Wai – putting water
at the centre. The second line states the vision: te mauri o te wai o Tāmaki Makaurau
– the life supporting capacity of Auckland’s water – is protected and enhanced.
The third line states five values:
- Ecosystems: Healthy water systems nourish the natural environment.
- Water use: We can meet our everyday water needs, safely, reliably and efficiently.
- Culture: Water contributes to our identity and beliefs, as individuals and
as part of communities.
- Recreation and Amenity: We enjoy being in, on and near the water.
- Resilience: Our communities, catchments and coastlines are resilient to
natural hazards and the impacts of climate change.
The fourth line of the table sets out four issues we need to work on: cleaning
up our waters, meeting future water needs, growth in the right places, and adapting
to a changing water future.
The fifth line of the table identifies four processes we need to work on: creating
our water future together, setting priorities for investment, achieving net benefits
for catchments, and applying a Māori world view.
The final line of the table sets out six principles to guide our work:
- Recognise that water is a treasured taonga
- Work with natural ecosystems
- Deliver catchment based thinking
- Focus on achieving right-sized solutions with multiple benefits
- Work together to plan and deliver better water outcomes
- Look to the future

From ridge to reef: taking a systems approach
Mai i ngā kahiwi ki ngā pūkawa: he tokonga ā-pūnaha te whāinga
This document considers water in all its different forms: in rivers and streams,
in underground aquifers, and in estuaries, harbours and marine areas. It talks about
drinking water, wastewater and stormwater - the 'three waters' that we manage most
directly.
Only one water
Sometimes we need to deal with different forms of water in different ways. But
they are all connected - there is only one water, constantly moving around the water
cycle. We want to make sure we think about how activities in one part of the water
system affect the health of the whole system. This is where we think an overarching
vision will help.
Taking a system-wide view is much easier to say than to do. Developing processes
to support us to keep the big picture in focus will be part of our challenge.

the region, from the ranges to the sea. There are rivers, aquifers, and harbours.

Water and the circular economy
Thinking about the whole water system aligns well with the circular
economy, described in the Auckland Plan 2050. A circular economy approach
means making the most of resources at each stage of their life cycle.
Resources are looped through many cycles of use, minimising waste and
capturing multiple benefits along the way.

Meeting current and future needs: the role of the council
Te tūtaki i ngā hiahia o ināianei anga atu ana hoki: ko te āhua
mahi mā te kaunihera
The council has a number of roles and responsibilities for water.
We work across the region to maintain, renew and improve our waters and our water
infrastructure. The decisions we make across the council family have big implications
for the health and the future of our waters. This includes council controlled organisations
like Watercare, Auckland Transport and Panuku.
Every day, we:
- provide safe, reliable drinking water to 1.5 million Aucklanders
- treat wastewater so that it is safe to release into the environment
- manage an extensive stormwater network, including the roads that helps to
divert rainfall away from people and property
- anticipate and manage the impacts of storms, floods and other natural hazards
- restore and protect our natural waterways.
Most of our work is focused on freshwater, land-based activities and the coast,
but we manage impacts on the marine environment too, by capturing and cleaning stormwater
before it reaches the sea.
In the next ten years, we expect to invest $7.1 billion in diverse water projects
of all sizes across the region.
We're always improving
Our approach to water is constantly developing. We seek to innovate where we
can, to find more effective ways to achieve the healthy, clean water outcomes our
communities want.
We work with other councils to learn together. We're pleased to be leading the
development of water sensitive urban design in Aotearoa / New Zealand. This includes
the Water Sensitive Design Guidelines.
Infographic text description
Auckland Council, Watercare and Auckland Transport look after:
- 365 million litres of drinking water per day
- 27 drinking water sources
- 450 million litres of wastewater per day
- 330,000+ manholes
- 474 rivers and streams
- 3200km coastline
- 9200+km of water supply pipes
- 8000+km of wastewater pipes
- 6300km of stormwater pipes
(Text description ends)
All of this work is shaped by the council's strategies, policies and plans, as
well as national legislation and policy (see fig i).
The main plans that we use to manage water are the Auckland Plan, the Unitary
Plan, the Long-term Plan and our Asset Management Plans. Together they provide the
direction, development rules, finances and work programme that determine the council's
activities. They also shape the activities of everyone else across the region.
The cultural significance of water to Māori is recognised in the Treaty of Waitangi
and in legislation including the Resource Management Act 1991, the Marine and Coastal
Area (Takutai Moana) Act 2011, and the Hauraki Gulf Marine Park Act 2000. These
Acts guide our approach to water at the council.

Water, water everywhere: the national conversation
He wai, he wai i hea katoa: te takinga kōrero ā-motu
Water is a big issue for Aotearoa. The national conversation often sets the direction
for regional and local efforts.
The National Policy Statement for Freshwater Management (NPSFM) is particularly
relevant. It requires all regions to safeguard the life-supporting capacity of freshwater
bodies and their associated ecosystems.
Te Mana o te Wai
The first objective of the NPSFM is 'to consider and recognise
Te Mana o te Wai in the management of fresh water'. This
is to ensure that the health and wellbeing of freshwater bodies is 'at the forefront
of all discussions and decisions about water'.
Te Mana o te Wai is the integrated and holistic
wellbeing of a freshwater body. Upholding Te Mana o
te Wai acknowledges, protects and enhances the mauri of the water.
It recognises the connection between water, people and the broader environment.
National reviews
Further national processes are currently underway to review how water is managed.
The Essential Freshwater Work Programme is focused on stopping further harm to freshwater,
reversing existing damage, and ensuring fair allocation of freshwater and nutrient
discharges. It is expected to result in amendments to the Resource Management Act
and the NPSFM, and introduce a new National Environmental Standard for Freshwater
Management by 2020.
The Three Waters Review is looking at how to improve the regulation and delivery
of drinking water, stormwater and wastewater to better support the prosperity, health,
safety and environment. of Aotearoa.
It is likely that the government will make changes to regulations, including
higher standards for drinking water, the discharges from wastewater treatment plants
and the stormwater system. They are also looking at changing how services are delivered.
Some of the options include creating publicly owned drinking water and wastewater
providers that operate across council boundaries.
These processes have implications for our water future in Tāmaki Makaurau: they
might change how our water services are regulated and delivered. The council is
an active participant in the national discussions, to ensure our region's water
needs are considered.
We have communicated our support for the government's position that drinking
water, wastewater and stormwater assets must remain in public ownership. We have
also identified that any subsidies needed to support smaller communities to meet
increased water standards should come from national revenue. Rates and local user
charges collected in Auckland should only be used to fund services in Auckland.

Implementing the Auckland Plan 2050
Te whakatinana i te Mahere a Tamaki Makaurau 2050
The Auckland Plan 2050 sets six outcomes and the development strategy for Tāmaki
Makaurau. It identifies the directions required to deliver the outcomes we want
to see by 2050, supported by focus areas for action. The Auckland Plan 2050 sets
the basis for the development of a water strategy for Tāmaki Makaurau.
Three challenges sit at the heart of the Auckland Plan:
Population growth: More than 1.66 million people live in Tāmaki
Makaurau already. Over the next 30 years this could increase by another 720,000
people to reach 2.4 million. The rate and speed of population growth puts pressure
on our communities, our environment, our housing and our roads.
Environmental degradation: Decades of pressure have had negative
impacts on the environment, including on our waters. This pressure will continue
to increase if changes are not made to the way that the environment is valued and
managed. Climate change will further amplify the challenges, with impacts such as
sea level rise, more frequent extreme weather events, and increased risk of flooding
and coastal inundation.
Shared prosperity: The success of Tāmaki Makaurau is dependent
on how well our prosperity is shared. As our population continues to grow, we need
to ensure that all Aucklanders can benefit from the social and economic prosperity
that growth brings and can participate in and enjoy community and civic life.
Infographic: The Auckland Plan 2050 at a glance

It sets out our key challenges:
- high population growth
- shared prosperity
- environmental degradation.
It identifies outcomes (what the plan aims to achieve):
- belonging and participation, Māori identity and wellbeing
- homes and places
- transport and access
- environment and cultural heritage
- opportunity and prosperity.
It explains the development strategy:
- how Auckland will grow and change over the next 30 years, including sequencing
of growth and development.
(Text description ends)
Better outcomes for water are supported across the six outcomes of the Auckland
Plan 2050, highlighting the need to take an integrated approach across a range of
areas. For example, one of the environmental focus areas is to restore environments
as Tāmaki Makaurau grows.

Getting our bearings: international comparisons
He whakamau i te ara whāinga mō tātou: ngā whakatauritenga ā-ao
whānui
How are other cities around the world thinking about their water futures?
To help us develop a locally-based vision, we have looked at international examples
of water visions and strategies. Many cities describe their aim as to become 'water
sensitive cities' or to apply a 'one water approach'. A look at comparable cities
reveals a number of themes - all of which could be readily applied to our water
situation:
- recognising water supports prosperity, community and economic wellbeing
- future-facing, aiming for inter-generational sustainability and resilience
- a priority on looking after the environment and ecosystems
- managing hazards and ensuring security of supply
- an integrated approach to decision making across the water cycle.
Some examples of water visions:
- 'Water is fundamental to our communities. We will manage water
to support a healthy environment, a prosperous economy and thriving
communities, now and into the future.' Water for Victoria (Australia)
- 'By 2040, London will manage its rainwater sustainably to reduce
flood risk and improve water security, maximising the benefits for
people, the environment and the economy.' - London Sustainable
Drainage Action Plan
- 'With our OneWaterSF approach, San Francisco will optimise the
use of our finite water and energy resources to balance community
and ecosystem needs, creating a more resilient and reliable future.'
- OneWaterSF (San Francisco)
In Australia, the Cooperative Research Centre for Water Sensitive
Cities has supported stakeholders to develop 'transition strategies'
for different cities. Each city process has defined its own vision,
with some commonalities:
- 'Adelaide is an attractive and resilient city that uses its
diverse water resources and knowledge to drive prosperity, sustain
healthy ecosystems, and connect communities.' - Vision and Transition
Strategy for a Water Sensitive Adelaide
- 'Sydney is a beautiful, prosperous and resilient city with thriving
communities, healthy ecosystems and cherished urban landscapes supported
by active water stewardship.' - Vision and Transition Strategy

A vision that speaks to this place
He whakakitenga e taki kōrero ana mō tēnei wāhi
What kind of water future do we want for Tāmaki Makaurau? A vision statement
helps us to define our destination and guide our choices along the way.
International examples affirm the issues and opportunities we have identified
here in our region. We would like to take an approach that is more clearly connected
to Tāmaki Makaurau.
Through the Auckland Plan and Long-term Plan consultations in 2018, Aucklanders
have provided their views of our water future. They emphasised that improving water
quality is an urgent priority for action. This is to improve environmental health
and recreational amenity. They also noted concern about the impacts of growth and
climate change.
Creating a vision
We want to create a vision that:
- is special to this place
- recognises the vital relationship between our water and our people
- recognises the role of mana whenua as kaitiaki within
the region
- represents values that can unify us in our actions
- sets a long-term aspiration for the way we take care of our waters.
The vision doesn't have to describe where we are today, but rather where we want
to get to.
We want to make sure that we align with the national conversation about water
and the objectives that have been set for us to achieve through the National Policy
Statement on Freshwater Management.
We are fortunate to have concepts in te Ao Māori that can help us express this
in a way that is unique to our place in the world. With the guidance of the Mana
Whenua Kaitiaki Forum, 'te mauri o te wai - the life supporting
capacity of water' has been identified as a concept that encompasses our aspirations
for water in Tāmaki Makaurau.
Te Mauri o te Wai
Te mauri o te wai has many layers. It is about the health
of water but also about the deep connections between water, the environment and
people.
Water has mauri - a vitality or essence that supports
life. The actions we each take can enhance mauri or, they
can diminish mauri.
In turn, the mauri of water affects the
mauri of people. When te mauri o te wai
is compromised, so are we. This is a concept that we can all connect to. Knowing
that some of our waters are polluted to the point where we can't safely fish, or
swim, or drink, is concerning for many Aucklanders. Te mauri o te
wai evokes a future where our children and grandchildren are able to swim
in, and harvest from, our rivers, estuaries and harbours.
While the National Policy Statement for Freshwater Management speaks of
Te Mana o te Wai, we think te mauri
o te wai is a better description of the aspiration that could unite us
in Tāmaki Makaurau. Waters with healthy mauri nourish us
and allow us to meet our obligations to care for one another (manaakitanga).
As mana whenua have observed, there can be no mana without mauri.
Guided by the Mana Whenua Kaitiaki Forum, we are proposing the following vision
as an aspirational statement of where we would like to be by 2050:
Te mauri o te wai o Tāmaki Makaurau - the life
supporting capacity of Auckland's waters - is protected and enhanced.
We appreciate that we might have many different ideas of how we protect and enhance
te mauri o te wai, and we believe this opens an exciting
space for discussion and collaboration. If we can agree a common destination, it
will become easier to debate the priorities and options to get there. It should
help us to recognise the consequences of actions across the whole water cycle, and
ensure we treat water as a precious resource.

The importance of water: describing our values
Te take nui o te wai: te whakaahua i ō tātou uaratanga
When we talk about values, we are describing what is important to us.
A value-based approach can help connect our decisions back to what we think matters
most. In this way, our values are our navigational aids, helping us to stay on course
towards our vision.
The National Policy Statement for Freshwater Management requires
that we develop values to inform the setting of freshwater objectives
and limits. This includes compulsory values of ecosystem health and
human health for recreation. These are used to inform the setting of
freshwater objectives and limits. We are proposing to
use the values we describe here as we develop Auckland's response to
the policy statement.
What our values look like
So, what is it that we value about water in Tāmaki Makaurau?
In the next few pages, we describe values for water in five broad categories:
- Ecosystems: healthy water systems nourish the natural environment.
- Water use: we can meet our everyday water needs safely, reliably and efficiently.
- Recreation and amenity: we enjoy being in, on and near the water.
- Culture: water contributes to our identities and beliefs, as individuals
and as part of communities.
- Resilience: our communities, catchments and coastlines are resilient to
natural hazards and the impacts of climate change.
Infographic text description
The five values arrayed around the vision, in a circle.
The values are: ecosystems, water use, resilience, recreation and amenity, and
culture.
The vision is: te mauri o te wai o Tāmaki Makaurau – the
life supporting capacity of Auckland’s waters is protected and enhanced.
(Text description ends)
On the following pages, we describe what it is that we value for each category,
and the current and future state of our waters compared to those values. We connect
the values to the 'big issues' (which we discuss in the next section). Finally,
we identify where you can learn more and suggest some simple examples of how you
can take action right now.
Ecosystems
What we value: Healthy water systems nourish the natural environment
Healthy streams, rivers, lakes and coastal waters are home to diverse plants,
animals, insects and other organisms. When the mauri of our
water is enhanced, and water systems are healthy, they can clean up contaminants,
absorb carbon dioxide, and provide us and other animals with the food we need to
survive.
Current state
The health and mauri of our waterways is very closely
connected to the activities that are happening on the surrounding land. Some streams
are surrounded by native bush and have clean water and thriving animal and plant
populations (see map).
By contrast, most of our urban streams are in poor health, with degraded
mauri. The health of rural waterways is mixed, depending
on how the surrounding farming, forestry and agricultural activities are managed.
Our estuaries, harbours and marine waters are home to diverse biodiversity, but
sediment from land-based activities are muddying the waters and smothering sea
life.
Fast facts:
- The Kaipara Harbour is the nursery for 98 per cent of snapper
off the west coast of the North Island.
- 80 species of birds roost around the Manukau Harbour, including
migratory birds like bar-tailed godwits. These birds fly continuously
for eight to 10 days to get here from Alaska.
- Marine reserves are proven to help biodiversity. The ecosystems
in the Goat Island Marine Reserve are healthier than many others
in the Hauraki Gulf. It acts as a nursery for the wider fishery
in the gulf. Around 11 per cent of young snapper in a 40km radius
the offspring of adults that lived in the reserve.
So, what's causing the degradation? It's not a simple picture. Sediment comes
from land disturbance like earthworks, forest harvesting, stream erosion and slips.
Many other contaminants accumulate from diffuse sources that are difficult to manage,
like the heavy metals that come from car brake linings. Roads are a conduit for
rain to wash these materials into the environment.
Map text description

The map highlights that poorer grades are generally more predominant in the urban
areas.
(Text description ends)
Although we are the nation's largest city, most of Tāmaki Makaurau is rural.
Agriculture, forestry and horticulture can increase the levels of sediment, nutrients
and bacteria in waterways. Even in natural forest areas, sediment and bacteria will
wash into our streams. The more sediment that is released at one time, the harder
it is for our ecosystems to recover.
Our ideas about what is okay have changed over time, and we are less accepting
of activities that were once quite normal, such as clearing native forests or tipping
waste into rivers. Now, we're learning about the impact of litter and microplastics
on wildlife.
Doing better
We've started to improve our impacts on ecosystems with:
- more water sensitive rural and urban development practices
- stock exclusion and nutrient management as part of good farming practices.

Infographic: Causes of degradation of our waterways
Infographic text description
Five icons and accompanying text describe ecosystem stressors:
- A cow. Rural activity: livestock, fertiliser, forest harvesting.
- A digger. Development: earthworks, paved surfaces, stream modification.
- A broken sewer pipe. Faecal contamination: Animals, birds, wastewater leaks.
- A car. Transport: brake linings, tyre abrasion, road runoff.
- A rubbish bin. Littering: litter, chemical spills.
Key impacts: sediment, nutrients, contaminants, heavy metals, pathogens, erosion.

Many of the actions we are taking for other reasons will also help water outcomes.
This includes Auckland Transport encouraging Aucklanders to use passenger transport
or walking and cycling to reduce the number of single occupancy cars on our roads.
We're innovating and learning as we go. Different treatment systems are being
trialled in the road corridor to treat the runoff before it reaches our harbours.
New technology brings new opportunities, such as using smart water sensors and drones
to carry out water monitoring programmes.
Case study
Like many urban streams, Te Auaunga / Oakley Creek in Mount Albert
has been known for its poor water quality. Over the last few years local
residents have been planting native trees around the stream. This helps
to reduce the amount of contaminants entering the water.
Recently students from Gladstone Primary discovered a spotty stonefly
nymph at the stream. These are usually only found in areas of native
bush and high water quality. Its presence is a reward for local residents,
showing their efforts are paying off.
Future challenges and opportunities
Continued population growth and urbanisation will add to the pressures on our
waterways. Land development is predicted to triple the amount of impervious surfaces
(hard surfaces like buildings and roads that stop water from soaking into the ground)
by 2048. Without careful design, this will increase the amount and speed of stormwater.
This could erode waterways and have bigger effects on receiving waters.
The impacts of climate change, such as increased temperatures and more frequent
storms will make it harder for our natural systems to recover after events.

Water use
What we value: We can meet our everyday water needs safely, reliably and efficiently
Access to clean water is essential to life, and critical for public health and
the economy.
In urban areas, we value having an efficient, trustworthy system that provides
safe drinking water as easily as turning on a tap.
In rural areas and on our islands, where we must manage our own water resources
from season to season, we value every drop.
We rely on water for sanitation, with a large-scale wastewater system that helps
to convey and treat sewage and minimise the risk of infectious diseases.
Current state
Where our water comes from
Providing Aucklanders with a secure supply of fresh water is one of the council's
most important jobs. Although it rains regularly, we do not have large fresh water
resources within the region: only 38 per cent of Watercare's municipal water supply
is sourced within the region (see fig iii). The rest comes from Watercare-owned
dams in the Hunua Ranges (part of the Waikato catchment) and the Waikato river.
Figure iii, map: Sources of Auckland's water
Map text description
A map showing the sources of Auckland’s drinking water, including dams in the
Waitakere and the Hunua Ranges, and the Waikato River. Circles on the map show where
the water is sourced from and the location of treatment plants. The circles are
sized according to how much water is supplied from each source. A boundary line
between Auckland and Waikato highlights that a large portion of our water is sourced
from the Waikato Region.
(Text description ends)
The last dam built to supply Aucklanders with drinking water was opened in 1977.
After the drought of 1993/94, Watercare undertook a detailed investigation of future
sources of drinking water. The Waikato River was selected as the best source and
a new treatment plant and pipeline was completed in 2002.
Today, our municipal system has proven to be safe, reliable and resilient. We
work hard to keep it that way, even in the most testing of situations (see box).
Case study
In March 2017, the Tasman Tempest dumped a record amount of rain
on Tāmaki Makaurau, peaking at two months' worth in only 12 hours. The
rain caused massive slips in the Hunua Ranges and filled the dams with
silt. The Ardmore treatment plant had to work a lot harder to get the
water up to drinking quality. Aucklanders were asked to cut down their
water use by 20 litres a day. Fortunately, the Ardmore plant wasn't
taken completely out of service, or more serious restrictions may have
been required. Watercare was able to draw on other dams to continue
supplying safe drinking water. Watercare is now looking at ways to reduce
slips including planting native trees, and treatment technology to handle
more silt from future storm events.
Our picture of rural water supply is less clear, because it's not managed in
the same way. Rural users source their own supply, from rain tanks, surface water
takes, or groundwater. The council issues resource consent for groundwater takes,
so we know that aquifers below some parts of Tāmaki Makaurau are nearly fully allocated,
which poses challenges for future water use.
For those using water tanks, storing enough water to last through summer can
be a real challenge. There can be periods when rain is not frequent or heavy enough
to replenish tank levels, and water has to be trucked in.
How our water is used
Watercare supplies around 365 million litres of water every day, for use in homes
and businesses. That works out to 272 litres per person per day, down 26 litres
since 2004.
More than half of that water is used in homes. At 160 litres per person per day,
we have the lowest per capita residential water use in Aotearoa.[1]
Volumetric charging (paying for water based on the amount that is used) encourages
us to be efficient. It also helps us to quickly detect when something's gone wrong,
like a broken or leaking pipe.
About a quarter of Tāmaki Makaurau / Auckland's reticulated water supply is used
by the commercial sector. Some industries are particularly water intensive, including
beverages, food and other manufacturing activities.

Fast fact:
By being water efficient, Aucklanders have managed to defer the need
for another water source by five years. Water efficiency gains by 2025
will buy us another five years.
Where our water goes
We also use water to transport our sewage, as wastewater. The mauri of wastewater
is diminished. If it mixes with other waters, it can pollute the mauri of those
waters too. Keeping untreated wastewater out of waterways is an important objective.
This is especially so for our ecosystem, and recreation and amenity values. For
the value of water use, we are interested in how our wastewater systems meet our
daily needs safely, reliably and efficiently.
Before waterborne sanitation was introduced, Aucklanders used cesspits and night-soil
carts. Because of this, residents suffered from regular outbreaks of typhoid and
other infectious diseases. The first sewerage system was completed in 1914 and was
an important milestone for public health (even if it simply moved the problem elsewhere).
Treatment plants today
Today, 18 treatment plants discharge around 450 million litres of treated water
each day. The flow from the largest plant at Māngere is comparable to some of our
bigger rivers.
Significant upgrades to treatment plants have greatly improved the standard of
wastewater treatment. As well as removing solids and biological nutrients, Māngere's
treatment processes result in a 10,000-fold reduction in harmful pathogens, bacteria
and viruses. The final effluent meets standards that protect public health, the
local environment, and coasts, estuaries and harbours.
Case study
Wastewater is now being valued as a source of energy and reusable
products. Water reuse at the Māngere and Rosedale treatment plants means
we don't need to use high quality drinking water for this low-grade
purpose. We save enough drinking water to supply 156,000 Aucklanders
every year. The plants also generate energy from biogas to power themselves
(56 per cent of Māngere's energy needs, and 74 per cent for Rosedale).
The goal: to run the Māngere and Rosedale plants on self-generated energy
by 2025.
Future challenges and opportunities
We expect that population growth will drive demand for safe, reliable drinking
water beyond supply by 2050. We will need to have new solutions in place. We currently
have limited prospects for increasing either supply or storage within our regional
boundaries. It is likely that we will need to use a mixture of tools to meet our
urban and rural water needs, including managing our demand and securing new sources.
We come back to this in 'Meeting Future Water Needs'.
The wastewater network and plants are also going to approach their design capacity.
We can add further capacity, and need to think about the best ways to do this.
As our city grows, decisions about where and how this happens can have a big
influence on how easy or expensive it is to provide water services. Getting water
and wastewater to where we need it to go relies on infrastructure which is expensive
to build, maintain and operate. We come back to this in 'Growth
in the Right Places'.
We will also need to ensure that our current water sources remain fit to drink
from, especially from smaller-scale bores and rural water takes. As groundwater
allocations reach their limits in some places, we need to ensure farmers and growers
are able to meet their water needs. They need to continue their important contribution
to the economy and food systems of Tāmaki Makaurau. This includes thinking about
how allocation is fairly managed, for example between existing and new activities.

Recreation and amenity
What we value: We enjoy being in, on and near the water
Spending time in or around water is one of the benefits of being an Aucklander:
we are never more than 20 kilometres from the coast. The recreational possibilities
and amenity value of our beaches, harbours, lakes and streams are highly prized.
They enhance our place as one of the world's most desirable cities to live.
Current state
Access
The waters of Tāmaki Makaurau are very actively used for recreation. Popular
spots like Piha and Long Bay receive more than 10,000 visitors a day at peak times.
Some of our popular recreational spots, like the west coast lakes, are also highly
sensitive natural environments. There is a challenge to manage demand without undermining
the very qualities that visitors enjoy.
To help people enjoy the water, the council provides facilities like boat ramps,
jetties and carparks. To help people stay safe, we support essential services such
as Surf Lifesaving and the Auckland Rescue Helicopter. The council's community facilities
delivered 400,000 swimming lessons last year.
Public health
Sometimes water gets contaminated with human and animal wastes. This can make
people sick, and is a source of considerable public concern. Some of this we can
fix (like broken sewer pipes and under-performing onsite wastewater systems), and
some (like bird droppings) we cannot.
These older areas of the city were built with combined stormwater and wastewater
services (only two per cent of the serviced area). The Central Interceptor and Western
Isthmus water quality improvement project will help with wet weather overflows.
New technology and better information makes it possible to detect and improve
small-scale wastewater issues too, such as broken pipes and leaks.
Safeswim has been developed to help people make informed choices about where
and when they swim. This is a partnership project with Surf Lifesaving Northern
Region and the Auckland Regional Public Health Service. Data from sensors on the
wastewater network is combined with predictive modelling to provide the public with
the best real-time information possible. Safeswim also allows Aucklanders to monitor
progress towards our target of more swimmable days and better public health.
Case study
In 2018, the council and community of Clarks Beach banded together
to find and fix the sources of contamination that were polluting their
beach. Locals regularly collected water samples to feed into Safeswim.
The causes of pollution are being traced, and the long-term alert on
the beach has been lifted.
Amenity and connection
In urban and suburban areas, we are working to make hidden waterways visible
again. There are great ways to reconnect our communities with their natural environment
and enhance mauri. Some of these include daylighting and naturalising our streams,
providing pre-treatment for stormwater, and building boardwalks along esplanades
are great ways to reconnect our communities with their natural environment. They
are examples of mauri-enhancing actions.
Future challenges and opportunities
As our population increases, it will be important to maintain recreational and
amenity opportunities for all Aucklanders. It will also be important to manage increased
demand for recreational use of waterways, beaches and the associated public facilities
like boat ramps. Growth in tourism could add to these pressures such as hosting
more visiting cruise ships.
More urban development will put further pressure on the health of our waters,
and have an effect on their recreational and amenity values.
Climate change, coastal inundation and more severe storm events are likely to
undermine access to water for recreation. Already-sensitive environments will become
more vulnerable to the impacts of visitors.

Since they began in 2002, volunteers of the Watercare Harbour Clean
Up have collected 38 million pieces of litter from our waterways.

Think before you flush things down the drain. In 2016, around half of the wastewater
overflows in dry weather were caused by people flushing rubbish down the toilet
and pouring cooking fats, oils and grease down the sink.
Culture
What we value: Water contributes to our identities and beliefs, as individuals
and as part of communities
For the many cultures that are part of Tāmaki Makaurau, our waters add to our
vitality and identity. They allow us to express our traditions. Being able to connect
with water in places that are special to us, whether that's through swimming, surfing,
fishing or gathering shellfish, is part of what makes us an Aucklander. It's also
what we like to share with our visitors.
Our cultural attitudes shape how we value and use water. If healthy waterways
are valued within our culture, we will place a higher priority on their protection.
Water holds particularly special cultural value to Māori. Mana whenua are iwi
and hapū who have a genealogical relationship (whakapapa)
to significant local waters. They have an obligation as kaitiaki
to protect them as taonga tuku iho (treasures to be passed
down to future generations).
Current state
Population increase, sedimentation and pollution have all had an impact on the
cultural value of water, over a long duration. Water with degraded
mauri reduces the quality of our experience. Swimming at
a litter-strewn beach, or fishing in murky water diminishes our cultural wellbeing.
This has adversely affected mana whenua and their ability to exercise
manaakitanga. Caring for guests is an important sign of mana
(prestige and authority), and relies on gathering food from traditional harvesting
grounds (mahinga kai).
Initiatives in two of our harbours are bringing the cultural values of communities
and mana whenua into decision-making processes:
- Sea Change - Tai Timu Tai Pari, a marine spatial
plan and initiative for the health and sustainability of the Hauraki Gulf, with
mana whenua views woven throughout all aspects of the plan.
- The Integrated Kaipara Harbour Management Group, created to ensure a healthy
and productive Kaipara Harbour.
Tikanga codifies Māori values into traditional practices and customs,
to ensure that the mauri of water is not degraded. Tikanga is commonly
based on experience and learning that has been handed down through generations,
and its practice can vary between iwi and hapū.
Case study
The sewage system that was opened in 1914 helped to reduce the problem
of typhoid and infectious diseases in the city. It also created new
problems. The system fed to an above-ground wastewater pipeline that
was built across Ōkahu Bay, against the wishes of the Ngāti Whātua Ōrākei
iwi. It discharged raw sewage into the bay, polluting the shellfish
beds, and turned the papakainga (village) into
a swamp during heavy rain. The pipeline separated the people from their
mahinga kai and contributed to a loss of mana
for their hapū.
Future challenges and opportunities
Population growth and climate change could put further strain on the cultural
values of water. These values include mana whenua's ability to gather kai from traditional
food grounds.
Changing attitudes to water may play a big part in how we manage our water resources.
Recognising significant natural features as a person in the eyes of the law could
help to ensure the long-term protection and restoration of significant water bodies.
The Whanganui River is an example of this.
Treaty settlements are creating new co-governance and management arrangements
with Iwi Authorities. These arrangements recognise Māori values as a fundamental
driver for the sustainable management of natural resources.

Resilience
What we value: Our communities, catchments and coastlines are resilient to natural
hazards and the impacts of climate change
We value resilience in our water systems, both natural and engineered. We want
them to continue working through sudden shocks and more gradual shifts in conditions.
Tāmaki Makaurau is vulnerable to a range of hazards that can risk our safety
and our daily lives. Intense storm events, coastal erosion, and localised floods
remind us of this.
We value our ability to weather such events with the least possible disruption.
When disruptions do happen, we value being able to recover quickly and effectively.
Current state
The hazards
Storms, flooding, coastal inundation and droughts, are natural processes. They
only become hazards when they affect the things that we value. These things include
property, infrastructure, and - most importantly - our safety.
In some places, we have made the impact of natural hazards worse. We've done
this by reclaiming coastal land, modifying landscapes, increasing impervious surfaces,
and building in vulnerable locations.
Hazard events can be localised and frequent. Nearly every year, we will experience
a damaging flood or other event somewhere in the region. This brings disruption
to affected households and businesses. Some parts of Tāmaki Makaurau are more vulnerable
than others.
Fast fact:
Floods are the most frequent and costly natural disasters in Aotearoa
/ New Zealand. 137,000 buildings in Tāmaki Makaurau / Auckland are prone
to some form of flooding, of which 16,000 are at risk of flooding above
floor level.
Water infrastructure
The resilience of our infrastructure is an important consideration. We want to
avoid disruptions to essential services such as drinking water supply and wastewater
disposal. Floods can make roads impassable, and pose direct threats to our safety.
These can be localised problems or have region-wide consequences. This depends on
where the hazard occurs and how quickly services can be reinstated.
Case study
Five days of unusually heavy rain in March 2017 flooded more than
300 properties. Trees fell, slips blocked many roads, and more than
2800 homes were left without power.
In New Lynn, debris washed downstream and blocked a major culvert
under the Clark Street and Great North Road intersection. Stormwater
overflowed the culvert and flooded local buildings and residences. The
footpath and road collapsed into a very large sinkhole, and one multi-storey
building was so damaged that it had to be demolished.
Major urgent repair works were an opportunity to make things better
than before. The new and improved culvert has two levels, to cope with
regular flows and flash flooding. Embracing water sensitive design,
roadside plants are used to capture excess water and act as a 'biofilter'
by catching contaminants before they enter the stormwater system.
Communities
In the wake of the South Island earthquakes, we have learned a lot about the
community dimensions of resilience, including the need for:
- Connected communities. Communities that are better connected
to each other are better able to take care of each other in times of difficulty.
- Informed choices. Resilience requires that we are all able
to make informed choices about risk. The council is working with scientists
to develop robust data, such as flood mapping and coastal inundation and erosion
studies. We need timely and effective ways to share that information with Aucklanders.
Case study: Day Zero
Capetown's experience highlights how essential it is for our water
systems to be resilient. A normally well-supplied city, severe drought
dropped water storage levels close to the point where officials were
counting down to when they would need to turn off the taps.
On 'Day Zero,' residents would only be able to collect 25 litres
of water each from standpipes across the city. That drastic vision prompted
residents to halve their water use, delaying Day Zero for now.
The city is pursuing further water efficiency and diversifying its
water sources. The changes have come at significant economic and personal
cost, but highlight the ability of communities to respond when they
need to.
The five R's of Tāmaki Makaurau / Auckland's emergency management:
Reduction, readiness, response, recovery, resilience.
Future challenges and opportunities
Risks to resilience are expected to change over time. This is in part because
natural systems are dynamic and ever-changing, and in part because of climate change.
Sea level rise, changes in rainfall intensity and patterns, and more storms will
all intensify existing risks. For example, predictions for losses from coastal erosion
in different parts of the region range from 6m to 55m in the next 100 years. With
sea-level rise, these predictions extend to 200m in some areas. These kinds of changes
will have significant effects on the future of coastal properties and activities.

The big issues: what we need to work on
Ngā take nui: ngā mea hei mahi mā tātou
The challenges for each of the five values highlight just how much we need to
do if we are going to protect and enhance te mauri o te wai o Tāmaki
Makaurau.
As part of developing this discussion document, we talked with Councillors, local
board members, the Mana Whenua Kaitiaki Forum and staff from across the council
family.
We asked them, what the issues are that we need to tackle. We also looked at
the submissions from the Long term Plan and Auckland Plan 2050 processes.
Focusing on the big issues
From those sources, we have distilled four big issues that we think are at the
heart of Tāmaki Makaurau / Auckland's water future:
These are challenging issues that we can't afford to ignore. None of them have
a quick fix, and we don't yet have all the solutions that we need.
Making progress where it matters
We want to make sure that our work programmes are responsive to these big issues.
We also want to make sure that we are always on the lookout for new opportunities
to make progress. Developing an Auckland Water Strategy will help us to keep our
focus where it needs to be.
We start to talk about the issues on the following pages, and suggest some lines
of inquiry that we'd like to pursue as part of developing an Auckland Water Strategy.
We are proposing to work across the council and with mana whenua, stakeholders
and the community to develop better understanding of the issues. We want to come
up with options to move forward, and to implement the preferred approach. We'll
also look to define goals and outcomes for each of the big issues. That way, we'll
be able to evaluate whether we are making a difference.
We are interested to hear your views about whether we have identified the right
set of issues, and what kind of actions we should prioritise.
Cleaning up our waters
Our biggest ecological effects on water come from our activities on the land.
Contaminants wash down through catchments and into our waterways. This disrupts
ecosystems and damages mahinga kai. Faecal contamination
from humans, animals and birds poses health risks for recreational use.
What do we need to do on the land, to clean up our waterways?
A clear objective
Aucklanders want cleaner waters[2].
We want to be able to enjoy the water without risk of getting sick, and we want
to get pollutants out of the waterways.
We want to restore the biodiversity of our natural waterways, and have confidence
that our water infrastructure is providing reliable, clean drinking water.
A long-term investment
Cleaning up our waters is going to take time and money, and there's a connection
between the two. With more money we can move faster, with less it might take us
longer to get to our goals.
Through the water targeted rate, we have committed an additional $452 million
over the next ten years to deliver cleaner harbours, beaches and streams. The money
is funding programmes to improve stormwater systems, reduce wastewater overflows,
and rehabilitate urban and rural streams.
This is going to enable us to achieve in a decade what we had originally anticipated
would take thirty years, but this investment is only part of the solution: there
is still more to be done.
A targeted approach
The needs are going to be different across the region. It's going to take more
effort to clean the waters in some areas compared to others.
We take a risk-based approach to deciding how we stage our investments, for example
the places with the highest human health risk. How do we make these choices transparent,
with a level of reassurance that the objective of cleaning our waters applies to
the whole region, even if its implementation has to be staged?
Our proposed action
We would like to explore how we can move further, faster with cleaning up our
waters. Some of the possibilities include better data-sharing, streamlining processes
to encourage water sensitive design, identifying other sources of funds, and stepping
up the effort to identify and fix sources of pollution.
Growth in the right places
Managing growth is the most pressing challenge for Tāmaki Makaurau. We need to
provide for the housing, employment and social needs of our growing population,
while meeting concerns about affordability and the environment. The impacts of growth
on water are significant: whether we like it or not, human activity inevitably has
effects on our waters.
What would growth look like if we made water - te mauri o te
wai - the priority in our decision-making processes? And are there changes
we can make to enable that kind of growth?
Our monitoring programmes tell us that water quality is usually best in the most
remote and natural parts of the region. It is worst in the most urbanised areas,
with a mixed picture in the rural and suburban areas in between.
An opportunity to improve
If our goal is to improve te mauri o te wai, we think
we need to do our best to protect the places where water is relatively healthy,
and use growth as an opportunity to improve the impacts on areas that are already
degraded.
Redevelopment in our town centres is a good time to address some of our existing
water problems, such as reducing flood hazards and improving stormwater capture
and treatment. It also helps us manage our infrastructure investments, concentrating
demand in a smaller area.
This approach aligns with the compact urban form promoted in the Auckland Plan
2050 and the Auckland Unitary Plan. It also lines up with our transport objectives
of increasing public transport patronage. The less time we are stuck in congestion,
the less pollution will come from our cars, onto our roads and into the sea.
Our proposed action
We would like to look further at the tools that are needed to manage and enable
growth in ways that will protect and enhance te mauri o te wai.
Meeting future water needs
We need to ensure we continue to have enough water to meet our needs, for drinking,
agriculture and industry, even as our population grows. We will also need to ensure
we are fairly allocating the water we have, across the range of water demands. This
includes making sure we leave enough water in streams and aquifers so they still
have enough 'base flow' to be healthy.
Where will our water come from by 2050?
Freshwater is a scarce resource in Tāmaki Makaurau, even though it rains frequently.
We have limited large rivers, lakes and groundwater resources in the region to draw
water from, and we are becoming increasingly reliant on the Waikato region to meet
our needs.
In urban areas, water demand is forecast to outstrip current supply within 10
years, prompting planned additions to our existing water supplies. This is expected
to meet our urban supply needs until around 2050, or longer if we can be more efficient
with our water use.
In the rural parts of Tāmaki Makaurau, we have a very limited understanding of
how much water is being used. This is especially important for groundwater, because
we think we are close to the limit of what we can sustainably take from aquifers
in some parts of the region.
Large water users meter their takes (as part of their resource consent conditions),
so we know that they aren't all using their full allocation. But, we don't monitor
small-scale bores. We also know there are many illegal bores.
Our proposed actions
We need to evaluate a range of options for meeting our future water needs. This
includes making the most of what we already have, and potentially developing other
new sources of supply. Because our supply options within the region are very limited,
the solution is likely to be a mixture of some or all of the following:
- more efficient water use (demand management)
- rainwater collection and storage, from rain tanks to reservoirs
- other water sources in the region, such as aquifers and surface water takes
from rivers
- water re-use for non-potable and potable purposes
- water sources from outside the region.
We would like to improve our groundwater monitoring, so that we can better quantify
demand and ensure our allocation systems are working and that our ecological effects
are appropriately managed.
Adapting to a changing water future
We know that conditions for our water future are changing, and that many of the
changes - like droughts, flash flooding and coastal inundation - will be rapid and
disruptive. We expect that effects will be felt unevenly across communities and
different industry sectors, due to geography, socio-economic status, and the level
of their water needs.
What can we do now, to anticipate the changes in our water future and be ready
to adapt? How much additional capacity (redundancy) do we need to build into our
systems, and how do we balance what is efficient today with what might be necessary
tomorrow?
Deciding what kind of approaches to take and where are not simple decisions.
They require a balance between:
- technical feasibility,
- affordability,
- community expectations, and
- health and safety.
There is also a dimension of timing. Today's hotspots require urgent responses,
but as the effects of climate change are felt, we can anticipate many more hotspots
emerging. How do we ensure our existing communities are able to adapt, and how do
we make sure that we're not still building in vulnerable places?
As is becoming evident nationally, it is not yet clear how the cost of adapting
to a changing water future will be shared between affected individuals and communities.
How should we prioritise our responses in Tāmaki Makaurau?
Coastal Management Framework
The Coastal Management Framework was approved in 2017. It is a good basis for
our thinking. It sets health and safety as a key consideration, then looks at whole
systems to understand what changes might be needed. It sets a long-term horizon
for change (100 years), and uses interim measures to work towards more durable solutions.
It recognises that not all technical solutions will be suitable, or even possible,
for all areas, and that what might work for ten to twenty years may need to change
over the longer term.
Our proposed actions
As the frequency and severity of hazard events increases, so will our need for
a shared understanding of risks, responses and the allocation of responsibilities.
We want to continue to develop this shared understanding with communities.
A hierarchy of responses
On the coast, there are four key approaches we can take: do nothing,
protect, adapt, and retreat. Here are some examples:
- Do nothing: No measures put in place
- Protect: Building seawalls and planting dunes
- Adapt: Raising buildings to account for sea level rise
- Retreat: Moving back from the coast

How we will work: applying a principles-based approach
Ka pēhea ā tātou āhua mahi: he tikanga ā-mātāpono te āhua whakahaere
mahi
We have a lot to do to make progress, both within the council and in partnership
with mana whenua, stakeholders and communities. We are proposing the following six
principles to guide us as we work:
- Recognise that water is a treasured taonga. Water is life,
and needs to be managed carefully to restore te mauri o te wai.
- Work with ecosystems. Working with the natural environment,
and mimicking its systems wherever possible is key to a water sensitive approach.
- Deliver catchment scale thinking and action. The catchment
is the best scale to think about water flows and uses, and the balance between
different activities and effects.
- Focus on achieving right-sized solutions with multiple benefits.
Local variables will drive the fine-grained responses to our regional
aspirations, with different solutions appropriate at different scales.
- Work together to plan and deliver better water outcomes.
We all have a stake in our water future. Engaging with mana whenua,
communities, and across disciplines helps find durable and effective solutions.
- Look to the future. Our planning and development takes
future uncertainties into account, so that communities and infrastructure are
future-proofed and resilient.
These proposed principles can be applied as we design and implement work programmes,
and as we evaluate progress. This will help to ensure the details of how we work
contribute to our vision and values.
Note: the Urban Water Working Group has proposed a series of ten principles
to support improved urban water outcomes across Aotearoa. The principles broadly
align with what we have proposed here. We will review the alignment when the draft
national principles progress to a final approved version.
Improving the way we work
We think that there are four key elements that we need to improve within our
processes, to help us apply the principles in our work:
As with the four big issues, we will need to work across the council and with
mana whenua, stakeholders and the community to identify steps we can take to improve
our processes.
Applying a Māori world view
Putting te mauri o te wai at the centre of our approach
to water means that we must incorporate a Māori world view across all of the elements
of our framework. So, how might a Māori world view shape our thinking and decision-making?
With advice from the Mana Whenua Kaitiaki Forum, we think there are three main
issues:
- placing te mauri o te wai at the centre of decision
making processes
- incorporating mātauranga Māori (Māori knowledge and
expertise)
- providing for mana whenua in governance arrangements.
We would like to explore how we might increase opportunities for mana whenua
to exercise their enduring kaitiaki role over the waters
of Tāmaki Makaurau. It could include a range of opportunities, from co-governance
arrangements to hands-on projects (some of which might be enabled through the council's
social procurement policy).
Creating our water future together
Achieving a healthy, sustainable and affordable water future for Tāmaki Makaurau
will require energy and commitment from all of us.
From the decisions we make in our own homes and communities, through to the regional
investment choices that we will need to make, we all have the opportunity to make
a better water future for Tāmaki Makaurau.
There are a few things that we know work well already:
- engaging Aucklanders in their communities, about their local water issues
- empowering Aucklanders as citizen scientists
- working directly with industry, agriculture and other sector groups to support
their leadership in water management
- ensuring we all take responsibility for our impacts, through pollution prevention
and polluter pays programmes
- collaborating across teams within council and with central government agencies
to ensure regulatory frameworks and practical projects are responsive to Aucklanders'
needs.
Case study: Pollution prevention
More than 1000 litres of purple dye was spilled into the Ōruarangi
Stream in 2013, killing all the eels, fish and many of the oysters.
The company responsible was fined $103,000 plus $25,000 court costs:
a significant example of the polluter pays principle in action.
Mana whenua, as kaitiaki of the awa, are working proactively with
the council to ensure such an accident isn't repeated. Through the Industry
Pollution Prevention Programme they advise businesses on how to prevent
contaminants entering waterways.
Setting priorities for investment
Water needs to be affordable and accessible to everyone. At the same time, we
have to be able to pay for our water systems. Put simply, we can't afford to do
everything today.
When we do spend money, we need to make sure that our spending lines up with
our objectives, and that we're getting value for money.
The next thirty years will require significant investment in our water infrastructure,
for drinking water, wastewater and stormwater. Between now and 2048, we expect to
have spent around $35.7 billion on water infrastructure. Rapid growth, historic
underinvestment in assets, and high levels of expectations from the community have
created significant financial challenges for the council.
Even without the pressure of anticipated population growth, we must continue
to maintain, renew and replace our current assets to meet communities' expectations.
This needs to be balanced with the community's ability to pay for the significant
investments that need to be made.
We would like to investigate whether taking a 'one water' view of the water system
would enable clearer prioritisation of our investments. Are there technological
innovations or opportunities for partnership that would allow us to get further
faster?
Achieving net benefits for catchments
Even with the best techniques, we can't avoid all water impacts from land-based
activities. This means that we need practical ways to balance our choices so that,
overall, our waterways end up better off than they started.
Looking at this picture at the catchment scale would allow us to understand where
impacts are coming from and - when impacts can't be avoided or remedied on-site
- how they can be mitigated or offset within a catchment.
For example, there may be opportunities to offset the impacts of new development
by protecting significant environmental sites within the same catchment. This is
about focusing our efforts on the activities that have the most impact on the whole
catchment health.
We also need to look at the regional scale, and make decisions about the level
of effect we can accommodate in different catchments. Te mauri o
te wai is different in every catchment, with their own mix of impacts and
abilities to absorb change (see Growth in the Right Places).
We would like to investigate practical methods to allow for decision-making at
a catchment scale. These could include offset mitigation, environmental compensation
schemes, and allocation and trading schemes.

What happens next
He aha ka whai muri ake
The council has decided to develop an Auckland Water Strategy. This discussion
document is an early part of that process. It reflects the current state of thinking,
and what we know about the issues for the waters of Tāmaki Makaurau.
We have proposed a framework to organise how we think and make decisions about
water:
- Our aspiration is to protect and enhance
te mauri o te wai - the life supporting qualities of
water. This sits at the centre of our values and drives our decisions.
- Five values. We recognise that we value water for a range
of reasons. We describe these in five categories, to help us understand how
the current situation measures up to our values, and to hone in on the stressors
that are having an impact.
- Four big issues. We identify four 'big issues' that define
our water challenge. If we are to restore te mauri o te wai,
we will need to address these issues.
- Six principles. We propose six principles that will guide
our actions as we move forward with developing the proposed framework into a
Water Strategy.
- Four processes. We also identify four elements that we
need to work on in our processes, to support quality decisions.
We have focused on high-level values in this document - the spaces where we can
find agreement and unify our vision. We would like to get some feedback and agree
on a framework as a way of organising our approach to what we do next.
The next steps in developing a Water Strategy for Tāmaki Makaurau need to provide
a line of sight, from vision to actions, to make sure what we are doing is going
to build the future we aspire to. Defining outcomes, measures and processes for
transparent reporting on our progress will be an important part of this.
Now, we want to hear from you:
- Do these values match what you value about water? Please tell us why, and
if there is anything else you value about water?
- How concerned are you about the 'big issues'? Please tell us why, and what
you think we can do now to anticipate and adapt to the changes in our water
future?
- What criteria are important to you as we develop options to meet our future
drinking water needs?
- What should we prioritise as we adapt to a changing water future?
- Do you have any feedback on the proposed framework, or is there anything
else you think should be included?
- What's the most important thing you think we should do for our water future?
You can give feedback online at akhaveyoursay.nz.
We are also running Have Your Say events across the region or you can fill out a
submission form available at libraries, service centres and local board offices.
Feedback must be received by 19 April 2019. We’ll take all the feedback to the Environment
and Community Committee later this year, as part of shaping the next steps in developing
an Auckland Water Strategy. To receive updates about this discussion, sign up at
