For the past 30 years, the disease has existed on Great Barrier island off the coast of Auckland however it has recently spread to the mainland, and can now be found in Auckland & Northland
This micro-scopic fungus (Phytophthora taxon Agathis) can infect kauri of all ages, from seedlings to mature trees. The disease is spreads from the soil to the roots of trees, making it easily transmissible.
The only way we can help is by stopping the spread of the disease from infected trees to healthy trees. The disease can be carried in soil on your footwear, when walking near kauri trees and on the feet and the guts of animals.
