The quiet word nobody used
When the government announced the abolition of all 11 regional councils in November 2025, the word “amalgamation” appeared nowhere in the press release. RMA Reform Minister Chris Bishop talked about “Combined Territories Boards” and “Regional Reorganisation Plans” and “downward pressure on rates.” But when BusinessDesk asked him directly whether the reforms would work best if boards ultimately formed larger unitary authorities, Bishop replied: “I think that is a fair summation of the situation.”
So the government is engineering council mergers without saying the word. The consultation period closed in February. Legislation is expected mid-2026. And the regions most likely to move first are already treating amalgamation as a foregone conclusion.
The real question is not whether councils will merge. It is whether merging them will fix anything.
The numbers that broke the argument for the status quo
The case against fragmentation is no longer theoretical. The Auditor-General’s 2024 report on council performance laid out the damage in 2021/22 and 2022/23: operating expenditure rose 23% to $15.8 billion, finance costs ran 20% above budget as interest rates climbed, and employee costs at metropolitan councils blew out 18% over budget.
For businesses, the consent processing failure is the sharpest pain. Only 3 councils out of 67 processed 100% of building consents within statutory timeframes. Fewer than a quarter met resource consent targets. Every missed deadline translates directly into holding costs, delayed projects, and capital sitting idle. If you are a developer, a construction firm, or any business trying to expand, the fragmented council system is not an abstract governance debate. It is a line item.
Don Good, chief executive of the Waikato Chamber of Commerce, told Newsroom in April 2025 that voters are fed up with 15% rates rises and that “efficiencies and sacrifices must be found, and that will mean amalgamation.” That framing, amalgamation as commercial necessity rather than political preference, is the one that matters.
Wellington is already acting like it is done
The Wellington region has moved furthest. Mayor Andrew Little called a super-city “more likely than not” and was blunt about the reform’s intent: “I think the intention of this particular part of the reform is about putting further pressure on councils to think about amalgamation.”
Porirua Mayor Anita Baker was more direct still: “This is our chance to do it and do it once.” Lower Hutt Mayor Ken Laban pointed to the absurdity of 32,000 public service workers commuting daily across a region governed by five separate councils. By March 2026, non-binding referendums in Porirua and Lower Hutt showed voters supporting amalgamation discussions. Southland is also progressing a three-council merger.
Not everyone is on board. Upper Hutt Mayor Peri Zee has pushed back against the inevitability narrative, worried about losing local voice. That tension between efficiency and representation is real, and it will not be resolved by pretending it does not exist.
Auckland’s awkward precedent
Here is the problem the government’s efficiency pitch has to survive. Auckland’s 2010 super-city, the only comparable New Zealand experiment, did not deliver what was promised. The NZ Herald’s March 2026 analysis found staff numbers climbed higher than the eight pre-merger councils combined. Household rates bills increased 85% between formation and the most recent year measured, averaging 2.16% annually above inflation.
Infrastructure Commission strategy general manager Peter Nunns was direct: “You would expect to see some cost efficiencies in areas like road maintenance or building consent processing… we didn’t find that in the data.” The Commission’s 2022 report found council size has no bearing on cost efficiency.
That finding should humble anyone who thinks mergers alone will fix local government. Auckland got unified strategic direction. It did not get cheaper services or faster consents.
Merging is not enough without spending discipline
The reform touches three costs businesses care about: rates, consents, and infrastructure planning. On rates, the government has promised downward pressure, but Auckland’s trajectory suggests the opposite without hard spending constraints. The proposed rates capping mechanism is the lever that actually matters, and its design will determine whether this reform delivers or just rearranges the bureaucracy.
On consents, the Auditor-General’s data proves the current system is failing. Whether larger councils fix that or merely centralise the dysfunction depends entirely on whether reorganisation comes with process reform, not just org chart reform.
On infrastructure, fragmented governance has produced fragmented planning for decades. If the Combined Territories Boards produce genuine regional strategies, there is a real prize for businesses in reduced duplication and coordinated investment. That is a big “if.”
The government is right that 67 councils serving five million people is structurally indefensible. But Auckland proved that merging councils without constraining what they spend just creates a bigger entity with the same habits. Legislation lands mid-2026. The detail will tell us whether this is reform or rebranding.
