The short version: why is this happening now?
That is the question on everyone’s lips right now, and it is a fair one. The honest answer is: we do not know yet. What we do know is that something significant is under way, the pressure to merge is real, and the shape of local government in New Zealand is going to look very different by 2028.
On 5 May 2026, Local Government Minister Simon Watts and RMA Reform Minister Chris Bishop gave New Zealand’s 78 councils a blunt instruction: develop a plan to reorganise yourselves, or the government will do it for you. Chris Bishop’s message was unambiguous: “Lead your own reform, or we will do it for you.”
Councils have until 9 August 2026 to submit what the government is calling “Head Start” proposals, outline plans for how they intend to restructure. Those that do not submit anything face a government-imposed backstop process. Either way, regional councils will not be elected at the 2028 local body elections. That decision is already settled.
The government’s preference is for territorial and regional functions to be combined into larger unitary authorities, councils that handle everything from roads and libraries through to environmental regulation and flood protection under one roof. Auckland has operated this way since 2010. Several other areas, Gisborne, Marlborough, Nelson, Tasman, and the Chatham Islands, already do the same.
Where are proposals most advanced?
Wellington
Wellington is the region that has moved furthest and attracted the most attention. Wellington Mayor Andrew Little has said that if a referendum were held today, he would vote for amalgamation, combining Wellington City, Lower Hutt, Upper Hutt, and Porirua into a single metro council.
Non-binding referendums held in Lower Hutt and Porirua during the 2025 local elections showed majority support for exploring amalgamation. That gave political momentum to a conversation that has been building for years.
But the region is not speaking with one voice. Upper Hutt Mayor Peri Zee remains sceptical, concerned about the impact on rates and about Upper Hutt losing its local identity. The Wairarapa councils, Masterton, Carterton, and South Wairarapa, appear to be considering their own separate unitary authority rather than joining a Wellington super city. And Andrew Little himself has criticised the government’s August deadline as insufficient time for genuine public engagement.
The most likely Wellington outcome, based on current signals, is a metro merger of the four main urban councils, with Wairarapa going its own way, and Kāpiti Coast still to be determined.
Northland
All four Northland councils, Far North District, Whangārei District, Kaipara District, and Northland Regional Council, have been in amalgamation discussions well before the May 2026 announcement. Whangārei Mayor Ken Couper has framed this as an opportunity for a “for Northland, by Northland” solution. The likely outcome is one large unitary authority for the region, though a split into two councils has also been raised as a possibility depending on how community feedback lands.
Southland
Southland is in a slightly different position. The three southern councils, Southland District Council, Gore District Council, and Environment Southland, made a formal reorganisation request to the Local Government Commission back in 2024. That process is still under way alongside the new Head Start timeframe.
Invercargill Mayor Rob Scott has gone further, proposing two separate unitary authorities: one centred on Invercargill, and a second for the wider rural districts of Southland and Gore. Some mayors in the region are on board; others, including the Gore mayor, have raised practical concerns about splitting the regional council in two.
Waikato
Hamilton City Council voted on 28 May 2026 to work towards submitting a Head Start proposal. Three models are being explored: a merger of Hamilton and Waikato District based on their existing water services partnership; a three-way merger adding Waipā District; or a single council for the entire Waikato region. Hamilton Mayor Tim Macindoe has emphasised local identity and affordability as key considerations.
Bay of Plenty
In the Bay of Plenty, Rotorua’s council has already passed a motion to investigate becoming a unitary council, potentially alongside other Bay of Plenty councils. Rotorua Mayor Tania Tapsell has noted discussions are at an early stage and that no preferred configuration has been settled. Some discussion is also under way about whether Rotorua might link up with Taupō or South Waikato. Tauranga and Western Bay of Plenty are also in the mix.
Taranaki
New Plymouth, Stratford, and South Taranaki are reportedly working towards a joint proposal that would include absorbing the Taranaki Regional Council into a single unitary authority covering the whole region.
Nelson and Tasman
Nelson Mayor Nick Smith has long supported merging with Tasman District, Nelson voted for amalgamation in 2012; Tasman voted against. With government pressure now applied, Smith is again pushing the case. Tasman Mayor Tim King has been more cautious, suggesting his council may simply wait for the backstop process, noting that Tasman is already a unitary authority and that amalgamation “doesn’t necessarily save money and it doesn’t necessarily make everything magically better.”
West Coast
The West Coast councils are exploring options that may result in a split outcome, Grey District and Hokitika (Westland District) merging with the West Coast Regional Council, while Buller District potentially stands alone.
Hawke’s Bay
Hawke’s Bay has been discussing amalgamation for well over a decade. The current reform process has re-energised the conversation, with the region among the six that Chris Bishop named as having advanced discussions before the May announcement. No finalised proposal has been publicly confirmed yet.
Wairarapa
Masterton, Carterton, and South Wairarapa are exploring a stand-alone Wairarapa unitary authority. This would separate them from the Greater Wellington Regional Council, which currently handles public transport, flood protection, and pest control for the area. That separation comes with financial implications, and the councils are getting external advice on the costs involved.
Canterbury and Christchurch
Christchurch City has expressed interest in merging with neighbouring Selwyn and Waimakariri district councils. Reports suggest the conversations have not been entirely smooth — at one point a Christchurch councillor raised the idea of tolling roads into the city if neighbours did not want to participate.
South Canterbury and Otago
Timaru Mayor Nigel Bowen has urged South Canterbury councils — Timaru, Mackenzie, Waimate, and potentially Ashburton and Waitaki — to consider merging rather than wait for central government to decide for them. In Otago, the six councils — Dunedin City, Queenstown Lakes, Central Otago, Waitaki, Clutha, and Otago Regional Council — are yet to settle on a clear path.
What happens after August 2026?
Councils that submit Head Start proposals by 9 August will have their outlines assessed by Cabinet. Initial decisions on shortlisted proposals are expected by late 2026, with detailed planning through 2027. The aim is to have new structures in place before the 2028 local body elections. For councils that do not submit proposals, the government’s backstop process kicks in — Ministers have been clear that this is not an empty threat.
Common questions people are asking
Will my rates go down after amalgamation? Probably not in the short term, and possibly not at all. Auckland’s super city is the only comparable New Zealand example, and household rates there have risen around 85% since the merger in 2010. Wellington Mayor Andrew Little has been explicit: “I do not believe amalgamation would cut the rates, but over time a metro council would help us to manage costs better.”
Can communities vote on whether to merge? Communities can request a poll under the Local Government Act, and some councils have run non-binding referendums. But the government has signalled it will not let public votes delay the overall reform process. The backstop exists precisely so that reform happens even where local consensus has not been reached.
Do all regional councils get abolished? Yes. The government has confirmed that regional councillors will not be elected at the 2028 local body elections. Their functions will be absorbed into new or expanded unitary authorities.
What about councils that are already unitary authorities? Places like Auckland, Nelson, Tasman, Marlborough, Gisborne, and the Chatham Islands already combine regional and territorial functions. Their future role in the reformed system is still being worked through.
Will smaller communities lose their voice? This is the most contested question in the whole debate. Some mayors argue that community boards within a larger council can maintain local representation. Others, particularly in smaller towns, are worried their community’s needs will be drowned out once merged into a larger entity.
The bottom line
No mergers have been formally confirmed yet. We are in the proposal stage, councils are working out what they want to put forward, communities are being consulted at pace, and Ministers are waiting to see what lands on their desk by 9 August. What is clear is that the direction of travel is set. The question is no longer whether New Zealand’s local government will change, it is how it will change, and how fast.
