John Hart has been elected to represent Wairarapa on the Greater Wellington Regional Council, after a by-election held to fill the seat left vacant by the death of former mayor and long-serving local leader Adrienne Staples. RNZ
Hart will hold the seat for the rest of the 2025–28 triennium — the three-year term that local councils serve. He ran as a candidate for the Wairarapa General Constituency, with the council publishing his candidate profile ahead of the vote. Greater Wellington Regional Council

Greater Wellington uses the STV (single transferable vote) system, which works like this: voters rank candidates in order of preference. If no candidate gets enough votes to win outright, the lowest-ranked candidate is dropped out and their votes are redistributed to those voters' next preferences. This process repeats until someone has enough to win. In this by-election, it took five rounds of preference transfers before a result was clear. At the fifth and final round, Hart led with 3,282 votes after the exclusion of Plimmer. The runner-up, Olds, finished with 3,098 votes — a margin of 184. Wellington.Scoop
For those who track local body elections, the fact that this seat required five rounds of transfers is worth noting. STV often produces final-round margins that look comfortable but actually depend on how lower-order preferences flow. Hart's 184-vote final-round lead is modest by any measure, and the exclusion of Plimmer proved decisive in consolidating votes behind him rather than Olds.
Hart's background is in community-focused environmental work. He spent the past two years with the Wairarapa Catchment Collective, working with communities, catchment groups, landowners and councils across the region. A catchment group brings together people who live and work in a particular river or water catchment area to look after its land and water. Hart also chaired the Masterton District Council Climate Advisory Group and co-founded Fab Lab Masterton. RNZ
Greater Wellington Regional Council chair Daran Ponter said Hart brought "extensive experience working with communities, catchment groups, landowners and local government agencies across the region." RNZ
The by-election was triggered by Staples' death. Staples had been a long-standing figure in Wairarapa local government, serving as mayor and holding a regional council seat. Her vacancy required a full by-election process rather than a council appointment — meaning voters, not existing councillors, chose her replacement.
The context Hart enters is one where the council's Wairarapa-facing work is already active. Greater Wellington published news on 11 August 2026 about its flood resilience programme, which covers rivers, stopbanks and planting plans, and in Wairarapa specifically aims to strengthen connections between people, whenua and water. Greater Wellington Regional Council Hart's catchment-group experience aligns directly with that workstream, and his seat on council will give him a formal role in its governance rather than an advisory one.
The broader context here is that this is a straightforward local body by-election with no wider party-political implications. Greater Wellington Regional Council operates outside the parliamentary party system, and Hart was not running under a party banner. The interest lies in the profile of the winning candidate: someone whose recent career has been grounded in catchment-level environmental collaboration and climate advisory work at the district council level, stepping into a regional governance role where those issues are live policy areas.
Hart's move from community-based catchment work to a council seat also reflects a pattern that has become more common in regional government — candidates whose backgrounds sit squarely within the policy areas their councils manage, rather than arriving from a general local-government or business trajectory. Whether that translates into actual policy influence on the council floor is a separate question, and one the remaining term will answer.
The Wairarapa General constituency seat will next be contested at the 2028 local body elections.
