The politics of the Cook Islands takes place in a framework of a parliamentary representative democracy within a constitutional monarchy. The Monarch of New Zealand, represented in the Cook Islands by the King or Queen's Representative, was the Head of State; the prime minister is the head of government of a multi-party system. The nation is self-governing and are fully responsible for internal and foreign affairs. Since 2001, the Cook Islands has run its own foreign and defence policy.[1] Executive power is exercised by the government, while legislative power is vested in both the government and the islands' parliament. The judiciary is independent of the executive and the legislatures.
