Taioaliʻiseu Fiti Aimaʻasu

Taioaliʻiseu Taimalelagi Saunia Afoa Fiti Aimaʻasu is a Samoan politician who served as a member of the Legislative Assembly of Samoa from 2025 to 2026. He is a member of the Faʻatuatua i le Atua Samoa ua Tasi (FAST) party.

Aimaʻasu worked as a public servant in the Ministry of Justice and Ministry of Education for 13 years. In 2016 he resigned to establish a tourism business, Tai's Native Experience.

In March 2026, Aimaʻasu resigned from parliament to join the governing FAST party, triggering a by-election in the seat. According to the Electoral Act, members of parliament who switch affiliations during a parliamentary term are required to vacate their seats and must contest a by-election to re-enter the Legislative Assembly. Aimaʻasu said he based his decision on consultations with some of his constituents and his family. He subsequently filed an electoral petition against Vaʻai, accusing him of corrupt electoral practices. Vaʻai submitted a counter petition. The pair were both found guilty on 29 June.
