Kauri Ora: Quarry and Extraction Guidelines
Guidelines for quarry operators to help prevent the spread of disease to Kauri.
This guide provides best practice standards to mitigate the spread of PA, which causes kauri dieback disease, via quarry operations.
A precautionary approach is taken to manage the level of uncertainty around whether Kauri and the surrounding soil is infected or not.
National plan to protect Kauri
In August 2022, a National Plan was launched to help protect Kauri from the Phytophthora agathidicida (PA) pathogen. The National Plan includes 10 rules that apply to anyone who grows Kauri, goes into Kauri forests, or lives or works around Kauri. By following this guide and the rules of the National Plan, we can all help protect Kauri for generations to come.
Key rules for quarries and extraction
Obligation to report
Land occupiers are obligated to report unhealthy Kauri to Tiakina Kauri, an authorised person or their regional council (Rule 1).
PA Risk Management Plans
If your quarry or surrounds is already infected with PA or has a high risk of being infected, Tiakina Kauri may ask you to develop a PA Risk Management Plan to help reduce the risk of the PA pathogen spreading on your property (Rule 4).
Earthworks PA Risk Management Plans
If you want to undertake any earthworks within a Kauri Hygiene Zone you must have an Earthworks Risk Management Plan (Rule 5).
A ‘how to’ guide and a template for creating this plan are available at www.kauriprotection.co.nz/resources for both PA risk and Earthworks Risk Management Plans.
Obligation to clean items
Any person entering a Kauri forest and anything that comes into contact with the ground must be clean before entering and when exiting the area. Risk item means an object that may come into contact with soil (other than gravel), track surfacing or plant matter (Rule 8).
