The Taumata Arowai Register of Drinking Water Supplies is the official public register for information about drinking water supplies in Aotearoa New Zealand.  

Some drinking water supplies are not required to register until 2028 and may not yet appear on the register.

Supplies with a registration status of Lapsed have not completed their duties under the Water Services Act 2021 (the Act) to periodically confirm or update their registration details. The details for their supply are included on the register but may not be up to date.

Under special circumstances, suppliers can ask for information to be withheld from this register, which is why you may see the word ‘withheld’ in relation to some supply information.
