A by-election for the Wairarapa constituency of the Greater Wellington Regional Council in New Zealand is currently scheduled to be held on on August 21, 2026, following the death of incumbent councillor Adrienne Staples. This market will resolve according to the candidate who wins the 2026 Wairarapa constituency by-election for the Greater Wellington Regional Council. If the election results are not known definitively by December 31, 2026, 11:59 PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of credible reporting. In case of ambiguity, this market will resolve solely based on official election results as published by the Greater Wellington Regional Council (https://www.gw.govt.nz/).John Hart secured the Greater Wellington Regional Council Wairarapa constituency seat in the 21 August 2026 by-election, triggered by the death of incumbent Adrienne Staples. Under the single transferable vote system, Hart advanced through preference distributions to reach the required quota ahead of Alistair Plimmer, Colin Olds, Michael Birch and other candidates. His community and catchment group experience, combined with prior local governance roles, supported strong second and later preferences that consolidated support. Official results confirmed on 25 August align with the market's 99.6% pricing for Hart. Late procedural challenges or recount anomalies remain theoretically possible but lack supporting evidence at this stage.
