The bill arrives
Waitaki District Council spent months fighting over who should run its water. It tried to go it alone, got rejected by the Department of Internal Affairs, and in April 2026 rejoined the Southern Waters CCO partnership it had previously walked away from. The four-council entity now manages $684 million in assets across Waitaki, Central Otago, Clutha, and Gore, serving roughly 84,100 people.
The governance question is settled. The cost question is not. Waitaki ratepayers are now being consulted on rates increases of 19%, 27%, or 45% to cover a projected $14 million operating deficit. Even the lowest option costs the average ratepayer about $13 extra per week, nearly $700 a year. And that is before water charges are formally separated from general rates under the Local Water Done Well framework.
Councillor Sven Thelning was blunt when the council voted to rejoin Southern Waters: “It wouldn’t have mattered even if we’d gone in-house, or whatever option we picked. It’s going to hurt.”
Decades of can-kicking, one enormous invoice
Waitaki faces a $47 million water infrastructure bill just to meet Taumata Arowai’s drinking water standards, up from an initial estimate of $37 million. Across all four Southern Waters councils, the 10-year capital programme exceeds $475 million.
The council’s own debt position made the in-house option a non-starter. Debt was projected to hit $70 million by 30 June 2025, with $50 million of that water-related. Morrison Low modelling showed the council would breach its 175% debt-to-revenue ceiling by 2027/28 under the in-house model. The DIA rejected the plan accordingly.
How did it get this bad? The previous council had proposed a 7% rates increase knowing it would not cover costs. Ray Henderson, chair of the Oamaru Ratepayers and Residents Association, noted that “the council had long tried to keep rates as low as possible and that had now come back to bite current ratepayers”. Mayor Mel Tavendale acknowledged the council is “at the stage where there’s not a lot more we can cut”.
Reform savings are real but marginal
The CCO model does deliver some relief. Morrison Low projected cumulative savings of $627 million by 2054 across the four councils. Waitaki’s own modelling showed savings of around $100 per household in the first year of CCO operation, rising to $200 by 2033/34. CCOs can borrow up to 500% of revenue, far beyond what councils can access, which is the whole point.
But $100 to $200 a year in savings against charges rising by hundreds of dollars annually is a rounding error, not a rescue. The reform changes who manages the debt and the pace at which it accumulates. It does not change the total.
Farmers face the sharpest edge
For rural businesses, the compliance dimension is particularly painful. The Stoneburn water scheme, established in the 1970s for stock water, serves 90 people and has been under a boil-water notice since 2023. Meeting drinking water standards would cost at least $1 million, roughly $30,000 per household. That is a regulatory compliance cost wildly disproportionate to what the infrastructure was designed to do.
Farmers Weekly captured the bind facing rural ratepayers: “the dilemma of swallowing a 19% rates rise to pay for upgraded water supply, or losing the opportunity to secure lower water project costs in the future”. Neither option is attractive.
Five hundred angry ratepayers and a national problem
More than 500 residents packed public meetings in Oamaru in early May to voice fury at the proposed increases. Some told the council they feared losing their homes. The Waitaki Ratepayers and Residents Association is calling for a government probe into the council’s finances.
Their anger is understandable but misdirected. Waitaki is not an outlier. Across the six districts originally assessed for a potential larger CCO, the 10-year capital bill tops $820 million. Any business in any council area with ageing water infrastructure, which is most of them, faces the same trajectory.
Councillor Thelning put it most honestly: “There’s a lot of work needing done out there, and it’s going to cost, and your elected council no longer has the ability to kick the can down the road, which is how we’ve got here.”
The debate over Three Waters versus Local Water Done Well, in-house versus CCO, four councils versus six, was always a debate about governance and optics. The pipes still need replacing. The only question the reform answered is who manages the pain. For provincial businesses modelling flat water costs over the next five years, Waitaki is the signal to stop.
