Warning alert

Severe weather events

We are working with water suppliers to manage the potential impacts of severe weather events on drinking water supplies. Your water supplier will let you know what to do if you are impacted. Who supplies your drinking water?

Informative alert

Clarification on Rules reporting

The deadline for annual reporting on the Drinking Water Quality Assurance Rules is 2 March 2026, or 40 working days from 31 December 2025. Our February stakeholder newsletter incorrectly reported this date as 25 February 2026.

Searchable guidance for drinking water suppliers, wastewater network operators, water carriers, laboratories and the public, including reference guides for managing information in Hinekōrako, our self-service portal.
