Dying kauri trees

DOC is responsible for protecting kauri on public conservation land and other land it manages, including many of New Zealand’s most significant kauri forests.


About the disease

Kauri dieback can kill kauri of all ages. It’s a disease caused by a microscopic fungus-like organism, called Phytophthora agathidicida (PA). It lives in the soil and infects kauri roots, damaging the tissues that carry nutrients and water within the tree, effectively starving it to death.

There’s currently no proven cure or treatment and nearly all infected kauri die.

The disease is easily spread through soil movements, eg when soil is carried on dirty footwear, animals, equipment and vehicles.

We can save our kauri forests by containing the disease and stopping it spreading to other areas.

Kauri dieback disease is found in the upper North Island. See the exact locations on the kauri dieback website.

What you can do to stop the spread

  • Stay on the track and off kauri roots.
  • Clean all soil off your footwear and other gear – every time you enter or leave an area with native trees, and at every cleaning station.
  • Use disinfectant only after removing all the soil.
  • Spread the word within your networks on how to stop kauri dieback. 
  • Get involved with the Kauri 2000 Trust.
  • More ways you can help save kauri.
