Public Register of Drinking Water Supplies
Our Public Register of Drinking Water Supplies includes some of the information that registered drinking water suppliers provide to us about their supplies. You can search and find the drinking water supplies in your local area in the public register.
Some drinking water supplies may not yet appear on the public register as we’re still working to confirm details of some of the almost 2,000 supplies that were transferred to us from the Ministry of Health.

Public Register of Wastewater Networks
Our Public Register of Wastewater Networks includes information on wastewater networks operated by councils or their subsidiaries, government departments and the New Zealand Defence Force.
It currently includes a limited range of network information but will be updated with more information in the future.

Ministry of Health Public Register of Drinking Water Supplies
The public register of drinking water supplies formerly maintained by the Ministry of Health was transferred to Taumata Arowai when we became the water services regulator on 15 November 2021. This register will no longer be updated but you can still view it here.
