How did the Cook Islands gain greater autonomy after 1965?

Following the transition to self-government in 1965, the Cook Islands gained greater autonomy by establishing itself as an independent political entity while maintaining a relationship of free association with New Zealand.1

This shift in status allowed the islands to expand their international presence and governance capabilities in several ways:

• International Relations: The Cook Islands began developing independent relationships with other countries in the region. They have entered into treaties as an independent political entity and joined various international organizations, including UNESCO and the Asian Development Bank.1
• Regional Cooperation: In 1971, the islands became a founding member of the South Pacific Forum, now known as the Pacific Islands Forum.1
• Diplomatic Autonomy: Although New Zealand remains nominally responsible for defense and external affairs, the Cook Islands has independently established its own diplomatic relations.2
• Governance: The 1965 constitution, which has been amended over time, established a unicameral Parliament and a cabinet led by a prime minister, providing a framework for local executive power.2
