The National Policy Statement for Freshwater Management 2020 requires regional councils to use wetland delineation protocols to establish the existence or extent of a natural wetland in cases of uncertainty or dispute.

This page also includes a New Zealand wetland delineation data form, and a quick reference guide to be used in conjunction with the form.
