About Drinking Water
Safe, affordable and reliable drinking water, and wastewater and stormwater networks that meet environmental and cultural expectations are the foundation of advanced societies. It is also essential for the protection of public health and the health of the environment.
In mid-2017, following the Government Inquiry into Havelock North Drinking Water, the Government established the Three Waters Review to look at how to improve the regulation and service delivery arrangements of drinking water, wastewater and stormwater – the three waters – to better support New Zealand’s environment, health, and safety. The findings of the Review were consistent with many of the Havelock North Inquiry’s findings and raised system-wide questions about the effectiveness of the regulatory regime, and the capability and sustainability of water service providers.
Taumata Arowai
This led to the establishment of Taumata Arowai, the new water services regulator and a strengthened regulatory environment for water services. Taumata Arowai has a strong focus on the safety of New Zealand’s drinking water and on 15 November 2021 became the drinking water regulator. In 2024, it will assume responsibility for wastewater and stormwater networks, becoming the three waters regulator for Aotearoa.

Three Waters Review
Beginning in mid-2017, the Three Waters Review ran in parallel to the latter stages of the Government Inquiry into Havelock North Drinking Water, which was set up following the campylobacter outbreak in 2016. Up to 5,500 people become ill, and four people are thought to have died as a result of this outbreak.
The initial findings of the Review were consistent with many of the Havelock North Inquiry’s findings, and raised broader questions about the effectiveness of the regulatory regime for the three waters, and the capability and sustainability of water service providers.

Government Inquiry into Havelock North Drinking Water
Safe drinking water is crucial to public health. The outbreak of gastroenteritis in Havelock North town supply in August 2016 shook public confidence in this fundamental service.
An estimated 5,500 of the town’s 14,000 residents became ill with campylobacteriosis and 45 were subsequently hospitalised as a result of this outbreak. Four people are thought to have died and an unknown number of residents continue to suffer health complications following this event.
The August 2016 outbreak was traced to contamination of the drinking water supplied by two bores in Brookvale Road, on the outskirts of Havelock North. This raised serious questions about the safety and security of New Zealand’s drinking water.
