Not everywhere in Aotearoa is water reliable and safe to drink. Every year in New Zealand, about 34,000 people get sick from contaminated drinking water. Many households still have to boil water to make it fit for human consumption. How is this going to be changed?

Enhancing Drinking Water Safety in Aotearoa: New Guidelines for Drinking Water Suppliers

New Zealand is fundamentally reforming the entire drinking water regulation system. New laws and rules have been introduced, baffling many drinking water suppliers. However, many small rural businesses, cafes, AirBnBs, dental surgeries and petrol stations do not even know they are a drinking water supplier under the new Water Services Act 2021.

Why is this, and what changes are happening in New Zealand’s drinking water supply network? Let’s bring some light in the dark and start with a quick overview.

The Water Services Act 2021

The Havelock North incident in 2016, which sickened more than 8,000 people with campylobacteriosis, was the catalyst for reforming the water supply sector in New Zealand. As part of the drinking water reform in New Zealand, the new Water Services Act 2021 (WSA) was commenced in November 2021. From this time on, this new legislation forms the statutory basis to improve drinking water safety in Aotearoa. Additionally, it provides the legal framework for Taumata Arowai, the new Drinking Water Regulator. This legal framework offers tools to reform the drinking water supply industry. Hence, the overall goal is to improve the performance of the water services sector.

Taumata Arowai – the new water service regulator

Establishing the new water services regulator Taumata Arowai is part of the Government’s Three Water Reform Programme. One of the three pillars is the new standalone Crown entity which has a supervisory role in New Zealand wastewater and stormwater systems. Since 2021, Taumata Arowai has taken over this responsibility from the Ministry of Health to regulate the water supply delivery system. Therefore, the overall goal is to improve the water services sector’s performance and ensure everyone’s water safety.

Drinking Water Standard of New Zealand

Drinking water is the most essential food! On average, an adult should drink two litres of water per day. In addition, we use potable water to prepare food and drinks. And we use it for personal hygiene, washing up or doing the laundry. Consequently, in New Zealand, drinking water needs to comply with the Water Services (Drinking Water Standards for New Zealand) Regulations 2022. These standards determine the maximum values for various contaminants, such as heavy metals or bacteria and other pathogens. Furthermore, the newly established Aesthetic Values consider additional components like the drinking water’s odour, taste and appearance.

Thus, Taumata Arowai sets the NZ Drinking Water Standards and ensures that drinking water suppliers meet their legal requirements to deliver potable water to their businesses, customers and communities. This water is free from any harmful impurities and is fit for human consumption.

Drinking Water Suppliers

As the Water Services Act 2021 gives clear definitions, it also outline the definition and duties of a Drinking Water Supplier.

Therefore, you are a drinking water supplier if you…

 supply drinking water through a drinking water supply.

 ought reasonably to know that the water you supply is or will be used as drinking water.

 are the owner and the operator of a drinking water supply.

 you are described in paragraphs (a), (b), or (c) and supply drinking water to another drinking water supplier.

Attention; this does not include a domestic self-supplier. In this case, it is a self-contained dwelling with its own drinking water supply. Serving more than a single household, e.g. having an office at home and seeing clients, you are considered a drinking water supplier.

Are you considered a drinking water supplier? What are your legal duties?

As a drinking water supplier, you must ensure that your water is safe and suitable for human consumption. The legislation allows you to develop a solution that applies the Acceptable Solutions from Taumata Arowai or complies with the Drinking Water Quality Assurance Rules 2022.

Water Services Act 2021 Compliance

Register your water supply with Taumata Arowai

All registered water supplies, regardless of their size, are given one year to confirm their registration and adhere to the requirements of the WSA.

Unregistered water supplies are allowed up to four years to complete their registration process and an additional seven years to fully comply with the WSA.

For any newly established water supply, immediate registration and full compliance with the Act are mandatory.

However, you need to renew your registration annually and update any changes in the supply details, including contact information, supplied quantity, new water sources, treatment methods, and more.

Hinekōrako, a user-friendly online service portal, has been introduced to streamline the registration process, as well as communication and notifications with Taumata Arowai.

Comply with the Drinking Water Quality Assurance Rules 2022

The Drinking Water Quality Assurance Rules derive from the Water Services Act 2021. Thus, they are a comprehensive framework providing clear instructions and guidance for drinking water suppliers to ensure drinking water safety. These new rules take into account the size and the distinctiveness of the water supply. Furthermore, they attach greater importance to water testing and monitoring the entire distribution system.

Part of the Assurance Rules is the establishment of a Drinking Water Safety Plan, a Source Water Risk Management Plan and a Backflow Prevention. Our water expert team is happy to assist you in demonstrating compliance with the Water Services (Drinking Water Standards for New Zealand) Regulations 2022 and the Water Services Act 2021.
