The proposed Drinking Water Standards (the Standards) will replace the existing Drinking-water Standards for New Zealand (revised 2018). They set limits for contaminants and other characteristics of drinking water. 
The Standards apply to all drinking water supplies regardless of the nature of the source water and the number of people served by the supply.

Detailed Summary

Taumata Arowai is conducting a public consultation on drinking water standards for Aotearoa; that will be made under the Water Services Act 2021.
