The programme aims to significantly reduce wastewater overflows into the Waitematā Harbour and reduce stormwater entering the wastewater network.
It involves numerous major infrastructure improvements to the stormwater and wastewater network in collaboration with Watercare.
Other goals include:
- reducing risks to public health
- opening both Meola Reef and Cox’s Beach from permanent closure
- reducing intermittent beach closures in this area over the next 10 years.

Contaminant reduction programme
This programme aims to reduce litter and pollutants in our waterways and marine environment.
Key aims include:
- reducing sediment in the Kaipara Harbour by improving stream stabilisation and preventing erosion
- reducing litter, sediment and heavy metals concentrations to Omaru Creek and Tamaki Estuary
- improving erosion and sediment controls on small building sites that would not otherwise be captured as part of monitoring and inspection
- reducing contaminants captured and transported in stormwater to help meet national water quality standards incorporated into the National Policy Statement for Freshwater Management.

Urban and rural stream rehabilitation programme
This programme aims to improve the health of streams and reduce contamination heading to our harbours.
It also involves:
- work to reduce erosion
- advance stream ecology
- improving environmental infrastructure.
This work will be carried out through community restoration initiatives, working with private landowners and restoring streams on public land.
Other aims include:
- improving the ecological health of streams
- enabling urban development in areas such as Omaru Creek, East Tamaki
- stabilising areas of high stream bank erosion
- reducing the amount of sediment in our harbours
- protecting property and infrastructure.

Onsite wastewater system compliance programme
This is a new regional compliance system requiring property owners with onsite wastewater systems to provide regular documentation that their units have been inspected and are in good working condition.
Proper maintenance reduces waterway contamination, especially in
streams and lagoons.
Water quality monitoring and system checks will continue in high risk areas.
Find out more on the Onsite wastewater system compliance page.
Where water quality poses a risk to public health – as indicated by the
Safeswim programme – Safe Networks conducts monitoring and investigations in our streams, watercourses and stormwater network to identify contaminants and track them to their source.
Where contaminants are identified as being from natural or non-human sources (for example, birds, dogs, stock), we look at options for management and control.
There is a high risk of poor water quality at our beaches, particularly:
- after heavy rain
- in areas serviced by ageing pipe infrastructure
- in areas with ageing onsite wastewater systems (private septic tanks)
- following long spells of dry weather when rainfall can carry dirty water to our beaches, including water contaminated with bird and dog faeces.
