The Selwyn Waihora water zone stretches from the upper Waimakariri basin and the high country around Lake Coleridge down to Te Waihora/Lake Ellesmere. The vision for Selwyn Waihora is to protect its alpine rivers and high country values and restore the mauri of Te Waihora while maintaining a prosperous land-based economy. Te Waihora and its margins are a taonga to Ngāi Tahu due to the high concentration of mahinga kai, wāi tapu and wāi taonga.
