The October 8 by-election for Tonga’s Niua 17 seat in the Legislative Assembly follows the resignation of the prior member after a court conviction for election bribery tied to the 2025 general election. Five independent candidates—primarily ‘Aminiasi Tonga Pau’u Tangimana, Paea ‘i Vaha Filimoehala, Sitiveni Selui, Sione Tuifio Hui, and ‘Aisake Hoatatau Finau—each draw support from distinct villages within the small constituency. Trader pricing reflects this fragmentation, with no candidate holding a decisive local base or incumbency edge ahead of polling. Village-level turnout patterns and last-minute endorsements remain the main variables that could shift the outcome in the final hours.
