This report provides flow-setting advice to Greater Wellington in relation to instream ecology to help inform the Whaitua Kāpiti process. It reviews and summarises existing information in light of modern flow setting guidelines developed to protect instream ecological values. Results were interpreted against an instream ecological (risk-based) flow-setting framework.

Note: Greater Wellington undertook this work as part of information gathering leading up to the Whaitua Kāpiti process. This is only part of the information base that the Whaitua Kāpiti Committee may have drawn from and is not considered to be definitive. The Whaitua Kāpiti Implementation Programme was completed in September 2024, for more information see https://www.gw.govt.nz/environment/freshwater/protecting-the-waters-of-your-area/whaitua-kapiti/#committee
