The National Pest Plant Accord (NPPA) is designed to prevent the sale, distribution and propagation of a set list of pest plants (the Accord list) within New Zealand. If allowed to spread further, these pest plants could seriously damage the New Zealand economy and environment.

The NPPA is a cooperative agreement between the Ministry for Primary Industries (MPI), the New Zealand Plant Producers Incorporated (NZPPI), unitary and regional councils and the Department of Conservation (DOC).
