Water conservation order
A water conservation order (WCO) is a legal ruling to protect aspects of water bodies. It may be to protect the quantity of the water itself or for any issues relating to the water body as a whole. Since 1984, sixteen WCOs have been passed, with a gap of 15 years between the last two: the 2008 Oreti River WCO and the 2023 Te Waikoropupū Springs WCO.
