Hinekōrako is not a replacement for Drinking Water Online

If you’ve been using Drinking Water Online (DWO), you should have received an email from the Ministry of Health, informing you that they’ll be closing this platform on 30 November this year.

We understand that several laboratories have been using DWO as a platform to organise sampling schedules and to store results. Hinekōrako will 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.

We recognise that the timing of this change may introduce challenges for you. We suggest that if you have any questions or issues regarding DWO that you contact the Ministry of Health who are responsible for the platform.
