For water suppliers
We're designing and building a new water services regulator. Taumata Arowai and the Ministry of Health are working together to ensure a smooth handover of the regulatory administration in late 2021.
In this section:
The current regulator of drinking water
If you supply drinking water, the Ministry of Health is the current regulator of drinking water.

If you need to speak with someone regarding your drinking water supplies, contact your drinking water assessor at your local Public Health Unit (PHU).
When Taumata Arowai is the regulator of drinking water
When the Water Services Bill is passed and Taumata Arowai takes over as the water services regulator (in the later part of 2021), registered drinking water suppliers will not have to do significantly more than they do now. Suppliers will still need drinking water safety plans – water safety planning will remain an essential step in understanding and managing the risks from supplying drinking water.
Suppliers who provide drinking water for 500 or more people must have a drinking water safety plan in place by the end of the first year that Taumata Arowai becomes the regulator.
All other suppliers have up to the end of year 5 (2026) to complete drinking water safety plans that comply with the new requirements.
Plans will not be approved by Taumata Arowai – suppliers are responsible for making sure their plans are effective and fully implemented. We will guide suppliers in preparing their water safety plans, and review and monitor them according to scale, complexity and risk.
Drinking water standards (the maximum acceptable values) will continue to be based on standards set by the World Health Organization (WHO). While we anticipate some changes, for example, to the way the requirements are structured and how compliance is demonstrated, these standards will not be significantly different to the current requirements.
Release of the proposed new drinking water standards and rules
The Water Services Bill proposes that Taumata Arowai has the authority to prepare standards and rules that water suppliers must comply with. We intend to release updated working drafts of new standards and rules by mid-October.
We're also preparing guidance to support the operational compliance rules and standards.
