National Pest Plant Accord

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.

The Accord List

• The table below compares the original (1995) NPPA list with the 2020 update. This shows what species have been removed and added.
• PDF links are individual pages from the 1995 list (now out-of-date).
• 2020 MPI links take you out to the current NPPA species profiles.
• Links from the botanical names are to sample pages from the Common Weeds of New Zealand book.
• The botanical names below have been updated to be consistent with the NZ Weeds Key.
