Lifted: Boil water notice for Rototuna Reservoir Area
Update
12pm Tuesday 7 October 2025
The boil water notice for properties in north-east Hamilton has been lifted as of 12pm today and the water is safe to drink.
Hamilton City Council has had three days of water tests that are clear of E. coli from the Rototuna reservoir and other sampling sites around the city.
This means drinking water for properties in Rototuna, Flagstaff, and parts of Queenwood in Hamilton, and Gordonton and Puketaha in Waikato District, no longer needs to be boiled for any purpose.
What you need to do
There are some steps you need to take before you start to use tap water as you normally would.
For properties on supplied directly from the network (i.e. no water tank):
Run all cold taps for five minutes
Run clean water through appliances like coffee machines, water dispenser and ice machines
Dispose of any ice
Maintain water filters according to the manufacturer’s advice (if you have one)
if you have a header tank for drinking water, empty and refill
hot water tanks do not need to be refilled
For properties on trickle feed supply or a water storage tank
You must take ONE of these steps before flushing taps or cleaning appliances.
Drain your tank, rinse it with clean water and then refill it.
Continue to boil water until the tank is completely refreshed.
Disinfect the water in your tank using additive-free bleach. The amount of bleach to use depends on the product. For bleach with 5% chlorine, use 33ml per 500L of water.
Some Choice News!
DOC is rolling out a new tool to help figure out what to tackle first when it comes to protecting our threatened species and the things putting them at risk.
Why does this matter? As Nikki Macdonald from The Post points out, we’re a country with around 4,400 threatened species. With limited time and funding, conservation has always meant making tough calls about what gets attention first.
For the first time, DOC has put real numbers around what it would take to do everything needed to properly safeguard our unique natural environment. The new BioInvest tool shows the scale of the challenge: 310,177 actions across 28,007 sites.
Now that we can see the full picture, it brings the big question into focus: how much do we, as Kiwis, truly value protecting nature — and what are we prepared to invest to make it happen?
We hope this brings a smile!

Will these roadworks affect you?
Don’t expect a quick trip between Cambridge and Tamahere for much of this year, because major roadworks are starting.
Asphalt works on that section of Waikato Expressway will run from March through to late 2026, NZ Transport Agency Waka Kotahi (NZTA) says. Motorists are warned to plan for significant delays.
“Unfortunately the pavement, particularly in the slow lanes, has deteriorated faster than expected,” NZTA’s Roger Brady said.
