Taumata Arowai

Safe drinking water for all New Zealanders and visitors to our shores is a reasonable expectation and high-performing drinking water, wastewater and stormwater services are essential for the protection of public health, and the health of the environment.

Recognising this importance, in September 2019, the New Zealand Government agreed to create a new water services regulator to administer and enforce a new drinking water regulatory system, while contributing to improved environmental outcomes from wastewater and stormwater networks.

In March 2021 Taumata Arowai was established as a Crown entity. Taumata Arowai will become New Zealand’s drinking water regulator, replacing the Ministry of Health, when the Water Services Bill is passed, which is expected to be in the second half of 2021.

Once Taumata Arowai is fully functional, it will:

  • Oversee and administer an expanded and strengthened drinking - water regulatory system to ensure all New Zealand communities have access to safe drinking water. That includes holding drinking water suppliers to account, if need be. See: For water suppliers (Taumata Arowai website).
  • Oversee, from a national perspective, the environmental performance of wastewater and stormwater networks. (Regional councils will remain the primary regulators of wastewater and stormwater).
