National Pest Plant Accord

A list of plants banned from sale, distribution, or propagation within New Zealand

The purpose of the accord is to prevent the sale, distribution, or propagation, within New Zealand, of specified pest plants.

The National Pest Plant Accord builds upon the initiative previously provided by the National Surveillance Pest Plant List, under which councils provided surveillance for a list of plants based on a mutual agreement to include them as pests in their respective regional pest management strategies.

The NPPA is a cooperative agreement between regional councils and government departments with biosecurity responsibilities, and the nursery trade.
