Taumata Arowai has appointed International Accreditation New Zealand (IANZ) as the accreditation body for laboratories under the Water Services Act 2021outbound.
If test results indicate that drinking water does not comply with the drinking water standards or compliance rules, accredited laboratories will notify Taumata Arowai and the drinking water supplier as soon as practicable.
If they are registered, the drinking water supplier must then comply with their statutory duties, most importantly taking immediate action to protect public health, notifying Taumata Arowai and taking all practicable steps to advise consumers of the issue and what they should do to protect their health (for example, boiling their drinking water).
