National Pest Plant Accord
For New Zealand to be able to trade internationally, Biosecurity New Zealand must be confident that the products associated with agriculture, horticulture, aquaculture and apiculture are free from unwanted pests and diseases.
The National Pest Plant Accord (NPPA) is a cooperative agreement between the Nursery and Garden Industry Association, regional councils and government departments with biosecurity responsibilities.
All plants on the NPPA are unwanted organisms under the Biosecurity Act 1993. These plants cannot be sold, propagated or distributed in New Zealand.

A great new resource for identifying National Pest Plant Accord species (NPPA) has just been released on-line at http://www.landcareresearch.co.nz/research/biosystematics/plants/nppakey/ 
The NPPA identification key is freely available thanks to funding from the Terrestrial and Freshwater Biodiversity Information System (TFBIS) Programme.
This key was developed over two years by Murray Dawson and Peter Heenan at Landcare Research, as well as Sheldon Navie (University of Queensland), Trevor James (AgResearch), and Paul Champion (NIWA). The interactive NPPA key covers the list of 150 plant species banned from sale, distribution, and propagation in New Zealand, along with 150 similar and related species. The key is illustrated with more than 5000 images and runs using 47 characters and 212 character-states.
