Local government amalgamation ultimatum: our 10 takeaways

On 5 May 2026 the RMA Reform and Infrastructure Minister Chris Bishop and Local Government Minister Simon Watts announced a new “Head Start” pathway enabling councils to propose their own local government reorganisation.

The announcement marks a significant shift from the Combined Territories Board approach announced in November 2025 and promises real consequences for councils that do not voluntarily engage. The process is closely tied to ongoing resource management reforms and seeks to fast-track amalgamation to realise benefits sooner rather than later.

10 key takeaways for councils

1. Three-month deadline. Councils have three months from 5 May 2026 until 9 August 2026 to develop and submit outline proposals for reorganisation. Ministers have made clear this timeframe is non-negotiable, urging councils to act fast in creating a proposal. This imposes real-time pressure considering potential consultation that councils may choose to undertake with their communities.
2. Voluntary but consequential. The Head Start pathway is voluntary, but councils that fail to submit credible proposals will be subject to a (yet to be determined) Government-imposed backstop process.
3. Focus on unitary authorities. Proposals must focus on creating larger, more efficient unitary authorities that combine regional and local council functions, streamline decision-making, and reduce duplication. There is no restriction on the number of unitary authorities that may be formed, but amalgamation is the clear requirement.
4. Joint proposals required. Proposals must come from groups of two or more territorial authorities representing either a majority of affected councils or a majority of the population in the area. Regional councils cannot submit proposals. Existing unitary authorities (excluding Auckland Council) can be part of a proposal.
5. Giving effect to local voice. The Government is intentionally leaving the pen with territorial authorities to begin with, to allow localised solutions to be proposed before central Government-led approaches are imposed. This follows the approach taken with the Local Water Done Well initiative.
6. Five assessment criteria. Proposals will be assessed against deliverability, support for the new planning system, simplification, economies of scale, and maintenance of a strong local voice.
7. No regional councillors by 2028. Ministers confirmed that regional councillors will not be elected at the 2028 local body elections.
8. Backstop for non-participants. Where councils do not come forward with their own proposal, the Government will implement a standardised approach, including transitional governance arrangements such as a board of mayors or other interim body (similar to the previously proposed Combined Territories Board approach).
9. Tightly linked to RMA reform. The reforms are designed to align with the new resource management system, which is expected to pass into law this year. Ministers consider it essential that planning reform and local government reform proceed together.
10. Timeline to implementation. Cabinet will agree in principle which proposals proceed later this year, with detailed design signed off in 2027 and changes implemented ahead of the 2028 local elections.

Of note, the Government has confirmed that key regional council responsibilities, including flood protection, emergency management, biosecurity and public transport will remain with local government. The Government is also planning to make a “significant investment in the digital backend” for council planning for natural hazards and flood-prone areas in one nationally accessible portal.

This announcement signals the kick start of a period of significant transformational change for local government. Some councils have already been moving towards amalgamation. Others are likely to struggle to meet the three-month deadline.

If your council is considering its options, whether participating in the Head Start process or preparing for the Government’s backstop arrangements, our Local Government team can advise on any aspect of reorganisation, including governance, transition structures, implications for resource management reform and compliance obligations.
