A by-election was held in the Gagaûifomauga 2 constituency in Samoa on 3 June 2022. It was won by Independent politician Foûisala Lilo Tuûu Ioane.
The by-election was triggered by the death of the incumbent member of parliament (MP) Vaûele Paûiaûaua Iona Sekuini of the Faûatuatua i le Atua Samoa ua Tasi (FAST) party, in March 2022. Originally five members were expected to contest the seat: Two members of the Human Rights Protection Party (HRPP), Soûoalo Umi Feo Mene, a former associate minister of justice who previously represented the constituency from 2011 to 2021, and Soûoalo Fineaso Poka. A single member of FAST, Lomia Tauloa Moafanua Siaaga, filed his candidacy. The remaining candidates consist of Independents Falesaopule Vaialia Iosua and Foûisala Lilo Tuûu Ioane. On 19 May 2022 Soûoalo Umi Feo Mene withdrew his candidacy to support Sooalo Fineaso Poka.
Pre polling commenced on 1 June. Voting began on 3 June, with a total of roll 2,031 registered voters. Polls closed at 3pm (), where a preliminary tally commenced. An official count took place the following day.
Falesaopule Vaialia Iosua, a former public servant who previously served as the assistant chief executive officer of the women's ministry, announced that he intended to address social inequality. Falesaopule, who also served in the ministries of health and education, sports, and culture, has promised to focus on improving access to water, education, and roads, to which he stated he would "fight for the roads in my district to be fixed should I succeed, some of the villages in my constituency have been waiting for years but to no success," On gender equality, he announced that he wants to enhance "economic women empowerment". Falesaopule also intends to increase efforts to decrease youth unemployment, which he said can potentially become disastrous for the constituency due to the relatively easy access these individuals have to alcohol. He said a prime focus would be to help vulnerable families, including individuals with disabilities.
Foûisala Lilo Tuûu Ioane, a farmer, and businessman filed his candidacy for the seat as an Independent. He wanted to contest the constituency in the 2021 general election but opted out for personal reasons. Foûisala said that he filed his candidacy for the by-election due to the encouragement from members of his village of Lefagaoaliûi and pressure from the village elders. He originally intended to run as a FAST member but opted to run as an independent when the party endorsed FAST contender Lomia Tauloa Moafanua. Foûisala announced that he would join FAST if victorious. He stated that he is a 'man who makes no promises' and supports the manifesto of FAST. Foûisala also expressed that he intends to implement policies proposed by FAST and said, "...the late M.P., Vaele had already cut the pieces of the cake for this constituencyâ¦so all that's left to do is for someone to step up and distribute it to the constituents".
Early results indicated an inconclusive race and showed Foûisala having a slim lead over the HRPP's Soûoalo. Final results showed Foûisala winning by over 60 votes.
