South Island councils want to redraw their own boundaries before the government does it for them

Twenty-seven South Island councils have sent the government 10 different plans for how they want to reorganise themselves, before a deadline that sees regional councils scrapped by 2028.

The plans were submitted to the government after a three-month window set in May. Across the whole country, 18 plans came in under the government's Head Start initiative (Beehive, 10 August 2026). Officials will now look at the plans and decide by the end of September whether they are realistic and give ratepayers better value (RNZ, 11 August 2026).

Local Government Minister Simon Watts said he was impressed by how many proposals came in. Approved plans will be signed off in 2027, with changes taking effect from the 2028 local elections.

Right now, most parts of New Zealand have two layers of local government: a regional council (which looks after things like water, air quality, and public transport) and a territorial or district council (which handles roads, rates, rubbish, and community services). The government's "Simplifying Local Government" reform removes the regional council layer entirely. Under the Head Start process, councils can voluntarily come up with their own plan for how to reorganise before that happens (Beehive, 5 May 2026). Plans will be checked against criteria that support national priorities like housing and infrastructure (Beehive, 25 November 2025).

Several of the South Island proposals involve creating what is called a unitary authority. That is a single council that does both jobs — the regional council's work and the local council's work — in one body.

Marlborough District Council and Kaikōura District Council agreed to form a partnership creating a unitary authority from 2028, with three councillors based in Kaikōura. Grey and Westland district councils put forward a joint plan for a unitary authority covering the whole West Coast, though Buller District Council split on the vote and did not back the plan (RNZ, 11 August 2026).

Nelson City Council and Tasman District Council did not submit a proposal. They already operate as unitary councils, so they were not part of the Head Start process.

The push for change has been building for a while. The Department of Internal Affairs published its final report on the Future for Local Government on 29 June 2023, proposing new council structures and ways of working. The Local Government Commission followed with a process document in February 2026 for its investigation into reorganising local government in Southland. Environment Southland announced on 5 May 2026 that councils had a three-month window to put forward their own plans. Southland District Council noted that a proposal needed at least two councils to submit together, with a deadline of 9 August.

The bigger picture here is a local government sector under real pressure to change. The government's timetable has regional councils disappearing by 2028, and councils have been given a fast-track chance to sort out their own structures before then (Thames-Coromandel District Council, 12 July 2026). C4LD, a local government action group with 27 member councils representing more than 1.3 million people, has been tracking the reform's progress (Horowhenua District Council, 5 August 2026).

The South Island plans show councils taking different paths within the same rules. The Marlborough-Kaikōura and Grey-Westland proposals both move toward unitary authorities that fold the two layers into one. Buller's split vote shows that even councils in the same region do not always agree on the best way forward.

Officials have a tight window to do their work. By the end of September, they need to weigh the 10 South Island plans plus the rest of the national proposals against criteria tied to housing and infrastructure. The deadline matters because any plan not approved through Head Start will go through the standard, slower reorganisation process. The 2028 local elections are the fixed point: councils that have not sorted themselves out by then will lose their regional council layer regardless of whether they put forward a plan.
