Protect our kauri trees

Kauri is a native New Zealand tree species.

Kauri is under threat

Only a tiny percentage of kauri forest remains in New Zealand due to extensive logging for many decades.

Kauri is now also under threat of kauri dieback disease (phytophthora agathidicida). This disease is a relatively new threat, but we can help reduce its spread by following the signs when visiting kauri forests.

For updated maps of track closures and kauri protection areas, see Waitākere Ranges Regional Park - Kauri Dieback Management.

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. 

 

 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).

 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.

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.

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.

 Kauri protection zones

To prevent the spread of kauri dieback disease, our Environment and Community Committee has closed some tracks and partial tracks so healthy kauri remain protected and undisturbed. Staff and rangers are working to identify more tracks to close.

A rāhui has also been placed over the Waitākere Ranges by iwi Te Kawerau a Maki. This cultural restriction by the mana whenua of the area urges people to stay away from the ranges to allow the forest to heal.

We support the principles of the rāhui and recommend using alternative walking and tramping tracks in the Auckland region.

Waitākere Ranges

42 tracks in the Waitākere Ranges are now closed to help prevent the spread of kauri dieback disease.

Long-term closures are in place for these tracks:

  • Anderson's Track
  • Arthur Mead
  • Browne Track
  • Chateau Mosquito
  • Christies Track
  • Clark Bush Track
  • East Tunnel Mouth Track
  • Farley Track
  • Ferndown Track
  • Filter Track
  • Forbes Track
  • Goodfellow Track
  • Hettig Track
  • Home Track
  • Kura Track
  • Lower Kauri Track
  • Maungaroa Ridge Track
  • McKenzie Track
  • Peripatus Track
  • Pole Line Track
  • Pukematekeo Track
  • Quarry Track
  • RGB Track
  • Sharp Bush Track
  • Tom Thumb By-Pass Track
  • Tom Thumb Track
  • Twin Peaks Track
  • Upper Huia Dam Track
  • Wainamu Bush Track
  • Waitākere Tramline Walk
  • Waitoru Reserve Track
  • West Tunnel Mouth Track
  • Zion Ridge Track.

Temporary ‘track closed’ signs are on as many tracks as possible. Rangers are working on permanent signage.

The following tracks are now permanently closed and will be decommissioned:

  • La Trobe Track
  • Robinsons Ridge
  • Summit Track
  • Nugget Track
  • Taumata Track
  • Walker Kauri Track
  • Bob Gordon Track
  • Lucy Cranwell Track

Odlins 2 Campground is also closed. All other campgrounds in the Waitakere Ranges remain open at present and are accepting bookings. However, this situation is currently under review and further closures are likely.

Hunua Ranges Regional Park
