Kauri propagation and planting

Guidelines to prevent the spread of disease to kauri when growing.

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 during the propagation and planting of Kauri (Agathis australis).

Advice for nurseries, commercial growers and community groups

Nurseries in other countries have contributed to the spread of Phytophthora pathogens because growing conditions at nurseries (e.g. high moisture and warm temperatures) favour pathogen growth.

Some of the current PA distribution in New Zealand may be due to historic movement of kauri seedlings and one nursery has already been found to be infected with PA.

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.
