Drinking Water Rules


Drinking Water Rules

    To help our members and the wider sector understand and work within the new rules, Water New Zealand has run a series of webinars on the new rules and other key topics. View past recordings or upcoming webinars here.   

    Draft Drinking Water Quality Assurance Rules  

    Note these rules are draft and won’t be enabled until July 2022 after consultation. Until then the existing NZDWS 2008 revised 2018 are in use. 

    The Draft Drinking Water Quality Assurance Rules set out the requirements that drinking water suppliers must meet as part of their responsibility to demonstrate that they are supplying safe drinking water. The Rules cover water quality operational requirements from source water abstraction to the point of supply to a consumer (not the consumer’s tap). Consultation on these rules will occur in the first quarter of 2022.

    If you are a private supplier you will need to register by 15 November 2025 and be fully compliant by 15 November 2028.
