The members of Parliament are elected by secret ballot on a “first-past the post” universal suffrage system. In 1980-81 the Constitution was amended by redefining the constituencies, thus increasing the number of members to 24. This was refined in 1991 where another constituency in Rarotonga was further divided into two to reflect a 25 member Parliament. The status quo remained until 2003 when the overseas constituency that was created under the 1980-81 Constitution Amendment, was abolished.
