Due to an electoral petition declaring the election of Tekii Lazaro invalid,[3] the 15th Parliament initially consisted of only 23 members. A by-election was held for the vacant Pukapuka-Nassau seat.
The Parliament sat for the first time on 18 February 2011.[4] It was dissolved on 17 April 2014.[5]
The Speaker of the 15th Parliament was initially former Prime Minister Geoffrey Henry.[6] Following Henry's death in May 2012, Niki Rattle was appointed Speaker.[7]
