The Taumata Arowai Register of Drinking Water Supplies is the official public register for information about drinking water supplies in Aotearoa New Zealand.  

Some drinking water supplies may not yet appear on the public register as we’re still working to confirm details of some of the almost 2,000 supplies that were transferred from the Ministry of Health. Once a supplier verifies their supplies in Hinekōrako (our self-service portal for suppliers and laboratories) they’ll appear on this public register.  

Under special circumstances, suppliers can ask for information to be suppressed from this register, which is why you may see the word ‘suppressed’ in relation to some supply information.
