This report provides a high-level introduction to state of water quality and ecological condition in the Waikanae River, Waimeha, Wharemauku and Te Kōwhai catchments. It outlines the land uses and ‘current state’ (mostly using data to the end of 2022) of water quality and ecology for river and stream environments, and summarises the known state and ecological condition of wetlands, groundwater, and estuaries.

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
