Which Auckland Suburbs Are Affected?
The boil water notice currently applies to parts of:
- Hillsborough
- Mt Roskill
- Royal Oak
- Three Kings
Watercare has clarified that not every street in these suburbs is included. Residents are being urged to check official maps to see whether their property falls inside the affected zone. Areas outside the marked locations can continue using tap water as normal.
Why Has Watercare Issued the Notice?
The warning was introduced after a routine water sample showed traces of E. coli. While all other test results remained within normal limits, Watercare decided to issue the notice as a safety measure while further investigations continue. Officials say there is currently no evidence of a wider problem across Auckland’s water supply.
According to Watercare, the move is purely precautionary and is designed to protect public health until more testing is completed. A further update is expected soon as testing continues.
What Residents Need to Do
Anyone living in the affected areas should boil tap water before using it. This includes water used for:
- Drinking
- Brushing teeth
- Preparing food
- Washing fruits and vegetables
- Making ice
- Washing dishes
Watercare says boiling water once in a kettle is enough to make it safe. After boiling, the water can be cooled and used normally. Bottled water can also be used until the notice is lifted.
Where to Get Safe Drinking Water
To help residents who cannot boil water at home, Watercare has set up public water tankers in the affected area. These are located at:
- 113 Duke Street, Big King Reserve
- Hillsborough Park Carpark, Carlton Street
Residents should bring clean bottles or containers to collect water. A third tanker has also been arranged to support a nearby retirement village.
What Is E. coli and Why Is It a Concern?
E. coli is a type of bacteria commonly found in the intestines of people and animals. Most forms are harmless, but some can cause illness if they enter the water supply.
Symptoms of E. coli infection may include:
- Stomach cramps
- Vomiting
- Diarrhoea
- Nausea
Young children, older people and those with weaker immune systems are considered most at risk. Because of these health concerns, even a single positive water test is taken seriously by authorities.
