National Pest Plant Accord


The National Pest Plant Accord is a New Zealand agreement that identifies pest plants that are prohibited from sale and commercial propagation and distribution.
The Accord initially came into effect on 1 October 2001 between regional councils and government departments with biosecurity responsibilities, but in 2006 was revised to include the Nursery and Garden Industry Association as a member of the decision-making body. Under the Accord, regional councils undertake surveillance to ensure the pest plants are not being sold, propagated or distributed.
The Department of Conservation also lists 328 vascular plant species as environmental weeds – species that infest, are controlled on, or are damaging to land under its control.
