Tiaki Wai set to open in the red as councils shift $1.7b debt
Friday, 27 March 2026
It is yet to fix its first leak, but Wellington’s incoming water agency is already poised to open in the red ‒ and may need a ratepayer cash injection as councils load $1.7 billion of debt on to the new entity.
Former Wellington City councillor Tim Brown, who is setting up a water users’ advocacy group, said “all five councils want to hand over as much of their debt as possible” to Tiaki Wai – which will replace Wellington Water as part of government reforms
It should have been able to keep its head above water, even with interest payments of about $91 million a year, but the Tikai Wai situation was “very ugly” and suggested either something major had happened or earlier forecasts were off-track, he said.
The consequences could be faster-rising charges to households or Tiaki Wai struggling to borrow in its own name and having to go to councils for guarantees, he said.

The water services strategy released on Wednesday showed the average Wellington region house would soon be receiving a $200 monthly water bill, rising to $566 within a decade.
It showed Tiaki Wai was expected to open with higher expenses than revenue. The situation has serious implications for how much it can borrow.
Tiaki Wai chairperson Will Peet warned the position needed to be improved “so we can operate with sufficient headroom to manage unforeseen events and meet our obligations”.
The board was going through a “critical” process with shareholding councils – Wellington City, Porirua, Hutt City, Upper Hutt and Greater Wellington – “to assess the available options and agree on a clear pathway forward”.
“The task for Tiaki Wai is finding the right balance between investing in improvements, repaying debt inherited from councils, and the level and speed of increases in customer charges,” Peet said.
“These are all interconnected and all contribute to the [revenue after costs]-to-debt ratio.”
Greater Wellington councillor Ros Connelly, the council’s Tiaki Wai representative, said the organisation’s financial situation largely reflected issues existing in the various councils.
“We are open to considering any proposals and to working collaboratively and constructively with Tiaki Wai,” she said.
“Our understanding is that such options may include a capital injection, reducing the level of debt transferred, providing a guarantee around forward commitments and an uncalled capital provision.”
The Tiaki Wai document, released on Thursday, showed forecast funds from operation (FFO) – the money left over after paying bills and other accounting practices – had been at 2.6% for the next financial year. But revised figures, after Tiaki Wai “establishment costs” were factored in, put this at -0.6%. It was previously at 4.3%.
The paper shows that the Local Government Funding Agency (LGFA) needs a FFO of 8% by 2030-31 to lend the organisation.
Tiaki Wai is taking over the ownership of water infrastructure from councils but also taking on the amount of debt councils carry for that infrastructure, amounting to about $1.7 billion.
Every resident of Porirua City, is set to hand over about $5200 debt to the new entity with the city shedding about 70% of its total debt. At the other extreme, each Upper Hutt resident will add $2236 to the new entity’s debt with the city handing over just 42% of its total debt.
A February 26 Porirua City Council paper said Wellington City could transfer just 33.5% of its debt on June 30. Council staff last year confirmed debt was expected to hit $2.1 billion in June. That would mean $705m going to Tiaki Wai, or $3350 per-person.
Each Hutt City resident will add $2583 with the council losing 51% of its debt.
Wellington mayor Andrew Little said there had been no request for a cash injection.
Upper Hutt mayor Peri Zee said councils were constrained with “limited options” under Government reforms.
