Note: The previously published Appendix to the Annual Report on Drinking Water Quality 2017-2018 which showed a suppliers compliance with the Health Act 1956 and the Drinking-water Standards 2005 (Revised 2008) was found to contain errors. These errors have been corrected and the Appendix has been republished
The Report describes the drinking-water quality of all registered networked drinking-water supplies that served populations of more than 100 people. It describes how these supplies met the requirements of the Drinking-water Standards for New Zealand and their progress towards meeting the requirements of the Health Act 1956 between 1July 2017 to 30 June 2018.
The report shows that for registered drinking-water supplies that served populations of more than 100 people:
- 3,250,000 people (84.7 percent) received drinking-water that complied with all the legislative requirements under the Act
- 3,810,000 people (99.3 percent) received drinking-water from a supply with a water safety plan for which implementation had commenced
- 3,751,000 people (97.7 percent) received drinking-water that achieved the bacteriological Standards which are the most important in protecting public health
- 3,531,000 people (92.0 percent) received drinking-water that met all the monitoring requirements in the Standards.
