Kauri Ora: Pruning and removing Kauri
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), which causes the fatal condition known as kauri dieback disease.
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.
This guide provides risk management guidelines to help mitigate the spread of the PA pathogen when pruning and removing Kauri or when carrying out arborist work near Kauri. The guide is intended to cover all aspects of arborist work. These guidelines are not policy but should be considered by planners, land managers, arboriculture industry, contractors and members of the public when undertaking pruning and removal of Kauri and are based on managing the risks associated with PA.
This guide is not intended for commercial forestry operations involving the removal of live Kauri.
National plan to protect Kauri
A National Pest Management Plan is the strongest form of protection for Kauri available under the Biosecurity Act 1993. A National Plan came into effect in August 2022 and includes 10 rules to mitigate PA spread for high-risk activities.
