The River Environment Classification (REC) is a system that classifies New Zealand's rivers according to their physical properties at a range of spatial scales. The development of REC has been supported by The Ministry for the Environment (MfE) and various regional councils to provide a spatial framework for environmental monitoring and reporting and river management.
Stream order is the numerical position of a tributary or section of a river within the entire network. Headwater streams are assigned a stream order of 1. When two tributaries of the same stream order meet, the order increments by one for the next section downstream. However, if two sections meet where one section has higher order than the other, the next section downstream has the same order as the highest upstream section.
