The Water Services Bill will provide a new regulatory regime for drinking-water suppliers, along with targeted reforms to improve the environmental performance of our three waters infrastructure. This bill will provide a clear leadership for drinking-water regulation through a new central regulator, Taumata Arowai, and will strengthen compliance, monitoring, and enforcement of the drinking-water system. It will create a requirement for a multi-barrier approach to protecting drinking-water supplies. It will include all drinking-water supplies in the new system apart from the domestic self-suppliers. It will ensure that source waters are protected and monitored. It will provide measures to significantly improve the transparency and environmental performance of our publicly owned three waters infrastructure. It will enable flexibility so the regulation of drinking water is proportionate to the scale, complexity, and risk profile of each drinking-water supply, and it will require those who have functions, duties, and powers under the bill to give effect to Te Mana o te Wai in a way that is consistent with the National Policy Statement for Fresh Water Management.
