Water services insights and performance

Taumata Arowai became the water services regulator for Aotearoa on 15 November 2021.

Drinking Water Regulation Report

We've published our first Annual Drinking Water Regulation Report, which includes a combination of data from the previous regulator, the Ministry of Health, and Taumata Arowai. The report relates to the period from the start of July to the end of December 2021. 

This report shines a light on the data and helps us understand the state of drinking water in Aotearoa New Zealand. The information and insights we report on will evolve over time and help to lift the performance of the sector to ensure that everyone has access to safe and reliable drinking water every day. 

The Annual Drinking Water Regulation Report for 2022 will cover the current calendar year and be published in early 2023. Registered drinking water suppliers will need to complete a concise compliance survey by the end of February 2023 to inform this report.
