The 12th Cook Islands Parliament was a term of the Parliament of the Cook Islands. Its composition was determined by the 2006 elections, held on September 27, 2006. It was dissolved for the 2010 election on 24 September 2010.
Due to an electoral petition declaring the election of Robert Wigmore invalid, the 12th Parliament initially consisted of only 23 members. A by-election was held for the vacant Titikaveka seat on 7 February 2007, and Wigmore was re-elected.
Due to a large number of electoral petitions and the need for a by-election to resolve the tied seat of Akaoa, the Parliament did not meet for the first time until December 2006.
Of the 24 Members of Parliament, three were women. The Speaker of the 12th Parliament was Mapu Taia.
Initial party standings
