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
- 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 you've removed all the soil.
- Stay on track and off kauri roots. A kauri’s roots can grow outwards 3 times as far as its branches.
- Spread the word within your networks on how to stop kauri dieback.
Infected trees may not show it – never assume anywhere is free of kauri dieback. If you’re in native bush and you’re in the upper North Island, it’s likely you’ll be near kauri.
There is no cure for kauri dieback, and it can be spread by just a pinhead of soil. But kauri will be saved – by people like you.
