By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 26, 2026|2 min read| Fact-checked

The Cook Islands are a self-governing parliamentary democracy in free association with New Zealand in the South Pacific Ocean. King Charles III is the head of state, represented locally by a King's Representative, and the country manages its own internal and foreign affairs while maintaining New Zealand citizenship for its people.

Political status

The Cook Islands are self-governing in free association with New Zealand, meaning they control their domestic government and conduct their own foreign affairs while retaining links to the New Zealand realm. The free association arrangement was established in August 1965, and while New Zealand retains responsibility for defence and some external matters in consultation with the Cook Islands, the islands manage their own internal and foreign affairs.

Government

The system is a parliamentary democracy with a prime minister as head of government and King Charles III as head of state, represented on the islands by a King's Representative. The prime minister is Mark Brown, as specified in the sources.

Parliament and elections

The legislature is the Parliament of the Cook Islands, which is unicameral and has 24 members elected from single-seat constituencies for four-year terms. General elections are held on a four-year cycle.

Traditional institutions

The House of Ariki is a consultative body made up of traditional leaders. It advises the government on customary matters, especially land use and related issues.
