Constitution Day is observed in the Cook Islands every August 4, celebrating the day the islands declared a self-governing nation in free association with New Zealand in 1965. The Cook Islands became a British protectorate in 1888 and were annexed by Britain due to fears of French occupation, later becoming part of the Colony of New Zealand in 1901. This holiday, known as Te Maeva Nui, meaning “a great celebration,” is the major holiday in the islands and is marked by various activities and events organized to honor the significance of self-governance. New Zealand remains responsible for the defense and external affairs of the Cook Islands, while the island's government handles its own laws. Since its inception, Constitution Day has grown in popularity and is celebrated with enthusiasm across the islands.
