This project is DOC's on the ground response to the disease killing kauri trees in the North Island. It aims to control the human spread of kauri dieback on public conservation land.

About kauri dieback disease

Kauri dieback is a disease is caused by a fungus-like organism and can be deadly for kauri trees of all ages. Kauri dieback lives in soil and infects kauri roots. 

Nearly all infected kauri die – there is no known resistance or treatment to the disease. 

The disease is easily spread through soil movements, for example, when soil is carried from one place to another on dirty footwear, animals, equipment and vehicles.

The best way to stop the disease is to control the transfer of soil on footwear and equipment btween diseased and healthy areas. 

DOC's response to kauri dieback

Our Kauri Dieback Recreation Project will control the spread of kauri dieback on public conservation land. This is part of a multi agency response lead by the Ministry of Primary Industries to stop the spread of kauri dieback.

We will work to save our kauri forests by containing the disease in its current locations and stop the spread into healthy areas. We are responsible for many of New Zealand’s most significant kauri forests, including Waipoua Forest, home to iconic Tāne Mahuta, the largest kauri in New Zealand.

We inspected 735 km of track that traverse kauri forests on public conservation land and identified 200 tracks that need kauri dieback prevention measures. 25 tracks will have on the ground work carried out in 2016-2017 amd the remaining 175 tracks within three years.

Measures that will be used to control the spread of kauri dieback on tracks include:

  • closures - temporary or permanent
  • improved signage
  • construction of boardwalks
  • reducing mud
  • installing cleaning stations to clean footwear
  • education and behaviour change.
