The National Exotic Forest Description (NEFD) provides a detailed description of New Zealand’s planted production forest to help with resource policy planning and industry development.

To maintain an authoritative, high quality database of New Zealand’s production forests.

The NEFD surveys known forest owners and managers with at least 40 hectares of planted exotic production forest. The survey is run on a two-yearly cycle, where all known forest owners with 40 or more hectares of forest are surveyed one year (census), and the next year only owners with more than 1,000 hectares (sample).
