Land disturbance activities around kauri

Guidelines for workers to prevent the spread of disease to kauri when working around kauri.

Kauri are under threat from a disease caused by the pathogen Phytophthora agathidicida (PA). The disease is also known as 'kauri dieback'. These guidelines will help avoid spreading the disease.

Managing the risks associated with land disturbance (earthworks) activities

Land disturbance activities such as earthworks, gardening, and undertaking tree removal near kauri are more at risk of spreading potentially contaminated soil than activities further away.

The disease can be moved in soil on roots of other plants, and by the equipment (including tyres) that is being used that may be contaminated with soil.

These guidelines apply to land disturbance activities where soil disturbance is likely to occur e.g. earthworks, gardening, and tree removal.

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 that causes ‘dieback’ disease.

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.
