Kauri tree removal and pruning
Guidelines to prevent the spread of the PA pathogen when removing or trimming Kauri trees.
Kauri are threatened by a soil-borne pathogen called Phytophthora agathidicida (PA for short), which causes the fatal condition known as kauri dieback disease.
Advice on how to protect Kauri from the PA pathogen when pruning or felling Kauri
These guidelines are for land managers, arborists and members of the public when undertaking Kauri tree removal or pruning. The guidelines are based on managing the risks associated with pruning and felling parts of a Kauri tree where PA is unlikely to occur (but we are not 100% certain) and to mitigate areas of the tree where PA is known to occur.
National plan to protect Kauri
Note: From 2 August 2022 ten new rules/regulations have been introduced as part of a National Plan to help protect Kauri from the PA pathogen.
More information on the Plan and how it affects operations on your land.
Research has underpinned the information in some of these guidelines. These resources will be updated in the coming months, with new guidelines to be developed.
