Water services insights and performance
Each year we produce two reports that provide an overview of the performance of drinking water, wastewater and stormwater networks in New Zealand.
Drinking Water Regulation Report 2024
This report covers the period 1 January to 31 December 2024. It includes data provided by drinking water suppliers about the safety and sufficiency of the water they supply from their registered drinking water supplies.
This report 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 appendix to this report includes the Water Services Authority – Taumata Arowai methodology for analysing the data supplied by councils.
Network Environmental Performance Report 2023/24
This report includes data and information for the period 1 July 2023 to 30 June 2024 provided by operators of publicly owned drinking water networks, as well as some information about public wastewater and urban stormwater networks.
This report provides insights into the environmental performance and impact of water services networks. This is the second time we have published this report.
