Protect our kauri trees

Kauri dieback disease is threatening the survival of our kauri – a native New Zealand tree species.

Kauri is under threat

Kauri trees are under threat from kauri dieback disease (phytophthora agathidicida).

The fungus-like organism is spread by just a pinhead of mud or soil, with major carriers being people and larger animals like pigs or goats.

What we are doing to reduce the spread of kauri dieback

We have taken significant steps to reduce the spread of kauri dieback in the Waitākere Ranges and Hunua Ranges regional parks.

The forested areas of the Waitākere Ranges Regional Park are now closed, with some exemptions where a Controlled Area Notice is in place from 1 May 2018. A list of tracks and their current status can be found below. 

A number of higher risk tracks in the Hunua Ranges Regional Park are also closed and from 1 May 2018 a Controlled Area Notice is also in place across the native forest area of the park. A list of these tracks and campgrounds can be found below. Further information and status of tracks.

Why we need to protect kauri 

Kauri trees are among the most ancient in the world. They can live for over 2000 years, grow to over 50m tall and have trunk girths up to 16m.

The kauri is taonga to Māori and European alike. The tree has spiritual significance both for its form and function. Maori regard it as a rangatira (chiefly) species because of its ecosystem-supporting role. Many other species depend on it. 

 

 Track and campground information

Waitākere Ranges

The forested areas of the Waitākere Ranges Regional Park are now closed to prevent the spread of kauri dieback disease. There are some exceptions in this area that are open under a Controlled Area Notice as of 1 May 2018.
 
A full list of tracks (both inside and out of the forested area) and their status can be viewed in the document below.  

The following Waitākere campgrounds are also now closed:​

  • Odlins 2 Campground
  • Opanuku Pipeline Campground
  • Whatipu Caves Campground
  • Karamatura Valley Campsite
  • Pararaha Valley Campground

All other campgrounds in the Waitākere Ranges remain open at present and are accepting bookings. However, this situation is currently under review and further closures are possible.  

Hunua Ranges

10 high risk tracks in the Hunua Ranges Regional Park are now closed to help prevent the spread of kauri dieback disease. They are:

  • Cossey Wairoa Track
  • Whakatiwai Ridge Track 
  • Whakatiwai Road Track
  • Lower Workman Track
  • Mangatangi Trig Track
  • Waharau Ridge Track
  • Mangatangi Ridge Track
  • Lower Link Track
  • Upper Link Track
  • Lower Mangatawhiri Track.

One track in the Hunua Ranges has been partially closed:

  • Kohukohunui Track - partial closure on the eastern side from Kohukohunui Trig Track junction.

We work with mana whenua Ngāi Tai ki Tāmaki, Ngāti Whanaunga, Ngāti Pāoa and Ngāti Tamaoho to protect the health of the Hunua Ranges/Kohukohunui forest. They support the closures and the track exceptions kept open under a Controlled Area Notice.

The following Hunua campgrounds are also now closed:

  •  Mangatangi Trig Campground
  • Workman Campground
  • Thousand (1000) Acres Campground
  • Adam's Lookout Campground

 Controlled Area Notices (CANs)

​CANs from the Ministry of Primary Industries are in place across the areas that will remain open in both Waitākere and Hunua regional parks.

CANs are a mechanism of the Biosecurity Act. In this case, any person entering the area must not have any visible soil on their footwear or equipment.

It also enforces the mandatory use of any hygiene stations provided at the track entrances and exits. Visitors should also remove all visible soil from their footwear and equipment when they exit a track.

Compliance officers will monitor the use of hygiene stations at entrances and exits. While officers do have enforcement powers, the initial focus will be on educating visitors on the requirements of the CAN.

Visit the Ministry of Primary Industries' kauri dieback website for more information on the CAN.

 Waitākere rāhui

​A rāhui was placed over Te Waonui a Tiriwa - the forested area of the Waitākere Ranges - by mana whenua Te Kawerau a Maki in December 2017, and remains in place.

A rāhui is a cultural prohibition, requiring people to keep away from the area.

It is a sacred means that mana whenua (local Maori with guardianship of an area of land) have of managing an "area of resource". It’s employed as a method of indigenous conservation, a means to protect the environment and allow time for the forest to heal.

The closed forested area of the Waitākere Ranges Regional Park is included within the rāhui.

 Kauri dieback disease

​This fungus-like disease kills kauri by spreading through spores in the soil.

The disease infects the tree through its roots and damages the tissues that carry nutrients within the tree. Almost all infected kauri die.

Scientists are working to find control tools for the disease. There is currently no known cure.

Know symptoms of kauri dieback disease

The disease is characterised by:

  • bleeding lesions at the base of the trunk
  • thinning canopy
  • yellowing leaves
  • dead branches.

If you see kauri with these symptoms, or want to request a kauri health inspection on private land, contact us on 0800 NZ KAURI (0800 695 2874).

 Managing kauri dieback disease

We partner with other councils and agencies to protect kauri through the kauri dieback management programme.

Surveillance

We conduct regular surveys to check the state of our kauri.

In recent years, we have had surveys at:

  • Waitākere Ranges Regional Park (2011, 2016)
  • Hunua Ranges Regional Park and Awhitu Peninsula (2012, 2017)
  • Hauraki Gulf islands (2013)
  • our local parks across Auckland (2014)
  • northern regional parks (2015).

Research

We also work on research projects to investigate:

  • how to detect kauri dieback from infected trees, contaminated soil and water
  • how to contain and mitigate impacts of the disease
  • control tools for treatment
  • long term impacts to forest ecology
  • methods of spread
  • origin of disease
  • potential impact on other species.

Education

We educate the public about the disease and its effects.

We work with communities to protect local kauri through advocacy work on regional parks. Come and talk to us at community events.

We also provide:

  • resource material for schools
  • activities for children
  • fact sheets and standard operating procedures for contractors
  • kauri care guide for landowners.

For more information, visit the Keep Kauri Standing website

Protection and control of kauri

  • We inspect and trial control treatments on private properties.
  • We carry out pig control in the Waitākere Ranges. Pigs spread soil microbes throughout our forests.
  • We close tracks to areas where healthy kauri remain in the Waitākere Ranges and Hunua Ranges. We also re-route and upgrade tracks when necessary and possible. See kauri protection zones on this page.
  • We have more than 200 phytosanitary stations in place to minimise the spread of the disease by forest visitors.

 How to protect healthy kauri

You can do your part in protecting healthy kauri and preventing kauri dieback disease from spreading.

Visitors of kauri areas

  • Clean your footwear, tyres and equipment before and after visiting our kauri forests.
  • Use cleaning stations every time you pass one as you walk in our parks.
  • Stay on the tracks and off kauri roots.
  • Stay away from closed tracks.
  • Don't remove soil from, or bring soil into, kauri areas.

Take particular care when visiting these healthy kauri areas:

  • Hunua Ranges
  • Auckland's northern regional parks
  • Waiheke Island
  • Hauraki Gulf islands - Kawau, Hauturu, Motutapu, Ponui.

Landowners with kauri

  • Make sure you and your visitors have clean shoes around your kauri. Avoid the roots as much as possible.
  • Fence off individual kauri or groups of kauri from people and animals (e.g. livestock) if appropriate.
  • Read the symptoms of kauri dieback disease on this page. If you see kauri with these symptoms or want to request a tree health inspection on your land, contact us on 0800 NZ KAURI (0800 695 2874).

Our tip

Phytosanitary stations have cleaning equipment so you can clean your shoes or gear that has had contact with soil. Always scrub off soil, then spray your gear.
