• On 26 November 2021 the 2021 Samoan by-elections were held, resulting in Aiono Tile Gafa (HRPP) being elected in Aana Alofi No. 2; Titimaea Tafua (FAST) being elected in Aleipata Itupa i Lalo; Maiava Fuimaono Asafo (FAST) being elected in Falealili No. 2; Laumatiamanu Ringo Purcell (FAST) being elected in Safata No. 2; Maulolo Tavita Amosa being elected in Sagaga No. 2; and Tagaloatele Pasi Poloa (FAST) being elected in Sagaga No. 4.^[12]
• On 29 November 2021, following the by-elections, the electoral commission declared Ali'imalemanu Alofa Tuuau (HRPP) and Faagasealii Sapoa Feagiai (HRPP) elected as additional members under the women's quota.^[13] Their election was disputed by the Speaker, but on 12 May 2022 the Supreme Court confirmed their election, and additionally declared To'omata Norah Leota (FAST) elected as an additional member due to the resignation of Leota Tima Leavai and her subsequent replacement by a man. The Supreme Court noted in its decision that when a man is elected to fill a constituency seat vacancy previously held by a woman, the constitutional requirement for a woman to be elected as an additional member is separate from the quota requirement. Thus there are now a record 7 women parliamentarians.^[14]
