**The Tongatapu 2 by-election, set for 8 October 2026, follows the Supreme Court’s upholding of bribery and campaign-spending convictions against former MP and minister Semisi Sika, who is barred from contesting for five years.** This created an open seat in the Nuku’alofa-area constituency after Sika’s 2025 victory over ‘Uhilamoelangi Fasi. Nine independent candidates registered in early September, including Samiuela Vea, Sione Harvard Tupouniua, Mounu Uaisele, Alvin Lafu Sika, Mele Teusivi ‘Amanaki, Malakai Matafonuafo’ou ‘Ofa ki Wakawaka Koloamatangi, ‘Ilaisa Lepolo Taunisila, ‘Olioni Manoa, and others. With no dominant frontrunner and all candidates drawing from overlapping village networks in Kolofo’ou, Haveluloto, Fanga-‘o-Pilolevu and surrounding areas, trader probabilities remain tightly clustered. The short campaign window, reliance on personal endorsements and local turnout, and absence of party structures limit rapid shifts, though late endorsements or candidate withdrawals could consolidate support and widen gaps before polling.
