Register your supply

How to register your drinking water supply and maintain your registration.

If your drinking water supply was registered with the Ministry of Health (MoH) immediately before 15 November 2021, you will need to check your migrated registration details. Different requirements apply if your supply was not registered before that date.

Hinekōrako is the primary channel for registration and management of drinking water supplies - allowing you to share information with Taumata Arowai.

Registered supplies

All drinking water suppliers (including water carriers) who were registered with the MoH immediately before 15 November 2021 will have their recorded drinking water supplies transferred to the Taumata Arowai register. This migration will happen automatically and will be administered by us.

We’ll send you an email asking you to review and update your contact and supply details. This process is being phased over time due to the number of suppliers and supplies involved. 

If you have not heard from us you can send an email to info@taumataarowai.govt.nz with your contact information, the name of your supply and its location.

You will need to use Hinekōrako - our online self-service portal to:

  1. create a user account  
  2. verify your migrated data
  3. complete your supply’s registration record.

Our initial focus will be working with registered suppliers to make sure they are able to meet their obligations under the Water Services Act 2021. In our first year it will also be important for us to learn from small, private and rural registered suppliers. We want to understand their challenges and support them to meet their obligation under the Act to submit a Drinking Water Safety Plan or use an Acceptable Solution by the end of the first year. 

Unregistered supplies

Drinking water suppliers who were operating immediately before 15 November 2021 but who were not registered with the MoH do not need to register yet. Unregistered suppliers (except water carriers) will need to register by November 2025 and fully comply with the requirements of the Water Services Act by November 2028.

If you transport drinking water please see For water carriers for information on how and when you need to register.

Temporary drinking water supply for an event

If you’re planning an event that requires a temporary drinking water supply, you can either use another registered drinking water supplier, provide bottled water, or fill out the Temporary Drinking Water Supplies form to register your own temporary drinking water supply for your event. Please note a new application is required for each event.

Find out more about your responsibilities if you intend to supply drinking water to people attending a planned event.

New drinking water supply

New drinking water supply

The owner(s) of a new drinking water supply that is going to start supplying water after the commencement of the Water Services Act 2021 must do the following before starting to operate the supply:

  • ensure the drinking water supply is registered
  • prepare and implement a drinking water safety plan that complies with legislative requirements and lodge a copy of the plan with Taumata Arowai.

The Act will apply in full to new drinking water supplies from the outset. Drinking water suppliers, including supply owners and operators, will need to comply with all applicable duties and requirements accordingly.

You can register now by filling in this form Application to register a Water Supply.

Once we receive and review your completed form Application to register a Water Supply, we may be in touch to request more information.

Who is responsible for registration

The drinking water supply owner (this can be an organisation or an individual) is responsible for ensuring the drinking water supply is registered. The owner(s) are those people with effective control of the drinking water supply. Some supplies will have one clear owner and other supplies may have multiple owners.

The owner can delegate the registration process to an agent or someone else who may be the supply operator. However the owner remains responsible for the accuracy of what is in the application and maintaining up-to-date registration details.
