The Drinking Water Regulation Report (DWRR) helps us understand the state of drinking water in New Zealand.
The Network Environmental Performance Report (NEPR) provides insights into the environmental performance and impact of water services networks.

It focuses the biggest risks identified in the Drinking Water Regulation Report 2024 (DWRR 2024) and outlines what suppliers need to do to address these. Namely, suppliers improving their systems, practices and infrastructure so that so that everyone has safe drinking water basics in place.
