Have your say on proposed updates to the Drinking Water Quality Assurance Rules

We’re consulting on proposed changes to the Drinking Water Quality Assurance Rules to make compliance clearer and easier to follow for large supplies (those serving 501 or more people), while maintaining strong public health protections. Find out more and have your say on our consultation site. https://korero.taumataarowai.govt.nz/regulatory/rules-review-large-supplies/

Hinekōrako is not a replacement for Drinking Water Online

We understand that several laboratories used Drinking Water Online (DWO) as a platform to organise sampling schedules and to store results. Hinekōrako does not offer this functionality as it’s been designed to support different legislation and a different regulatory approach. Under the Water Services Act, drinking water suppliers are responsible for ensuring compliance and for working with labs to organise sampling schedules. 

Hinekōrako has been designed to receive and store notifications and contact details but not to manage supplies or schedule sampling.
