The Local Government Minister has stepped in over Wellington’s looming water bills, saying soon-to-be-implemented charges are much higher than what officials were originally told to expect.
New water entity Tiaki Wai today announced its forecast charges, which will be billed separately to rates from late July, have the potential toclimb to $6831 annually in a decade’s time.
Tiaki Wai said it represents “really steep increases” for households but is needed to tackle historical underinvestment.
The new figures have caught the attention of Minister Simon Watts, who said this afternoon he is “concerned for Wellington ratepayers” after noticing the costs are greater than what was initially presented to the Department of Internal Affairs and the regulator.
In August 2025, Wellington’s councils submitted a water services delivery plan that set out proposed water charges.
Watts said he called Wellington Mayor Andrew Little this afternoon asking him to explain.
“I just outlined to him that we received a plan from you which outlined a profile of cost increases and as a result the entity has now published a price which was not in the plan, which is much higher,” Watts told reporters in Parliament.
“I need to understand and have an explanation around that”.

Watts said he has once again found himself concerned for ratepayers in the capital.
“We’ve got a long string of issues in this area and [when] someone presents a plan, I expect that that plan follows through.”
In response to the minister’s concerns, a Tiaki Wai spokeswoman said the plan released last year was based on “the best information available at the time”.
The spokeswoman said even the new numbers are based on several assumptions “and areas where substantial further work will be required to refine our plans”.
Speaking to the Herald this afternoon, Little said Tiaki Wai had been “forecasting higher operational expenditure right from the outset”, and the numbers did not come as a great surprise as they had been signed off by the organisation’s partners committee, of which he is a member.
“It’s been underfunded for a long time, so we did expect to see some quite significant increases,” Little said.
Little reiterated to the minister his desire for the Commerce Commission to be called in to oversee Tiaki Wai’s pricing, as is the case for Watercare in Auckland.
