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.
