Indicators at a glance: Drinking-water quality
This section summarises the latest Environmental Health Indicators about drinking-water quality and health in New Zealand.
Water contaminated with pathogens may cause disease, particularly gastrointestinal diseases.
Drinking-water supplies can be treated to remove pathogens and make the water safe to drink. The number of people on drinking-water supplies meeting the Drinking-water Standards for New Zealand is monitored annually.
Fluoride can also be added to water to help prevent tooth decay. In particular, children’s oral health can benefit from access to fluoridated water.
