Drinking-water Standards for New Zealand 2005 (Revised 2018).

Pursuant to section 69O(1) of the Health Act 1956, the Minister of Health has issued Drinking-Water Standards for New Zealand 2005 (Revised 2018) to supersede and revoke the Drinking-Water Standards for New Zealand 2005 (Revised 2008).

The availability of safe drinking-water for all New Zealanders, irrespective of where they live, is a fundamental requirement for public health. The Drinking-Water Standards for New Zealand provide requirements for drinking-water safety by specifying the:

  • maximum amounts of substances or organisms or contaminants or residues that may be present in drinking-water
  • criteria for demonstrating compliance with the Standards 
  • remedial action to be taken in the event of non-compliance with the different aspects of the Standards.

The Drinking-water Standards for New Zealand 2005 (Revised 2018) contain comprehensive information for owners and operators to assist in the management of public and private drinking-water suppliers and we strongly encourage you to become familiar with all aspects of them.

The Drinking-Water Standards for New Zealand 2005 (Revised 2018) now require routine monitoring of total coliforms; and enumeration testing for E.coli and total coliforms. In addition, there are a number of minor changes to the Standards to clarify or correct text within the Standards, to simplify compliance procedures, or to move material from the (mandatory) Standards to (voluntary) Guidelines.

The Drinking-Water Standards for New Zealand 2005 (Revised 2018) come into force on 01 March 2019.
