Register of drinking-water suppliers

Section 69J of the Health Act 1956 requires the Director-General of Health to maintain a register of specified drinking-water suppliers and specified self suppliers, and identifies the particulars that must be recorded in the register. The drinking-water register provides information about drinking-water suppliers and the types of supplies they manage.

The register can be viewed on the Institute of Environmental Science and Research Limited (ESR) website's Drinking-water Register for New Zealand.

Register of Recognised Laboratories for New Zealand

To demonstrate compliance with the New Zealand Drinking-Water Standards, water suppliers need to monitor the quality of their drinking-water by taking water samples and having them analysed. Section 69ZY of the Health Act 1956 requires the Director-General of Health to maintain a register of recognised laboratories that can analyse drinking-water, and identifies the particulars that must be recorded in the register.

The Register provides easily accessible information about the laboratories that have been assessed by IANZ and found to comply with either NZS/ISO/IEC 17025:1999 or the Ministry of Health Level 2 Criteria analytical laboratories.

The register can be viewed on the Institute of Environmental Science and Research Limited (ESR) website's Register of Recognised Laboratories.
