New Zealand Drinking Water Standards

The availability of safe drinking water is an essential requirement for all New Zealanders, irrespective of their status. The NZ Drinking Water Standards, as set by the Ministry of Health, provide requirements for drinking water safety by stipulating; (1) maximum amounts of substances or organisms or contaminants or residues that may be present in drinking-water, (2) criteria for demonstrating compliance with the Standards, (3) remedial action to be taken in the event of non-compliance with the different aspects of the Standards (Ministry of Health, 2018).

The standards as set by the Ministry of Health, contain broad information for owners and operators to assist in the management of public and private drinking-water suppliers. Moreover, the standard now requires routine monitoring of total coliforms; and enumeration testing for E.coli and total coliforms (Ministry of Health, 2018).
