What's Happening With Council Mergers Across New Zealand?
Sunday 9 August was the deadline for New Zealand councils to hand in their own plan for merging with neighbouring councils. Councils that did not submit a plan will have one forced on them by central government. RNZ
The government wants fewer, larger councils. The idea is that bigger councils can deliver services more efficiently and cost ratepayers less. Think of it like merging small businesses into one larger company — the goal is to cut overlap and share resources. Officials will now look at the plans councils submitted and decide whether each one is realistic and good value for money. The final plans are expected to be signed off in 2027, with the changes taking effect from the 2028 local elections. RNZ
Councils have responded very differently. Hamilton District Council voted 12 to three not to take part, meaning the government will decide its future for it. Christchurch City Council unanimously agreed to submit a plan. Wellington and Wairarapa mayors agreed to put two proposals to ministers. RNZ
A council also recently voted against submitting a plan alongside Tauranga City Council and against accepting the government-imposed process, according to reporting from 8 August. RNZ
In the Manawatū-Whanganui region, five councils agreed to work together on a joint programme rather than submit a merger plan. Palmerston North and Horowhenua councils proposed creating a new sub-regional council. RNZ
Whanganui mayor Andrew Tripe said Whanganui, Rangitīkei, Tararua, Manawatū, and Ruapehu chose not to amalgamate and would not let the government decide for them. Manawatū District mayor Michael Ford said 86 percent of the 750 people who responded to a council survey were against merging with any other councils. Nearly 90 percent were opposed to amalgamation outright. More than half refused to even say which council they would prefer to join if forced. Thirty percent chose Rangitīkei, and 10 percent chose Palmerston North. RNZ
The government announced this process in May. Local Government Minister Simon Watts and Resource Management Act Reform Minister Chris Bishop told councils: 'Today we are giving council's a clear choice. Lead your own reform or we will do it for you.' The Back Stop process — the one that applies to councils that did not submit their own plan — is expected to be finalised in 2027. RNZ Beehive
The Department of Internal Affairs, which is the government agency that oversees local government policy, published Cabinet materials on the process on 13 May 2026. It also maintains an official webpage called 'Simplifying local government'. Department of Internal Affairs
Former prime minister Helen Clark called the approach 'haphazard'. She pointed out that the Local Government Commission — an independent body that normally oversees council restructuring — is not playing a central role. There is also no Royal Commission, which is a formal independent inquiry, as there was when Auckland's councils were merged. RNZ
The broader context here is the push and pull between what the government wants and what local communities are saying. The Manawatū survey results show strong opposition — most people would not even name a council they would prefer to merge with. Ministers and officials will need to take that into account as they assess the plans. Councils that chose not to submit their own plan now face having the government design their future for them.
Clark's criticism adds a political angle. Without a Royal Commission or the Local Government Commission leading the process, the government is driving the reforms directly. For councils like Hamilton that opted out, the Back Stop process means central government will decide how their local governance is structured. Officials now begin the assessment phase, working out which plans are realistic and deliver better value ahead of the 2027 deadline.
