The culture of the Cook Islands reflects the traditions of its fifteen islands as a Polynesian island country, spread over 1,800,000 square kilometres (690,000 sq mi) in the South Pacific Ocean. It is in free association with New Zealand. Its traditions are based on the influences of those who settled the islands over several centuries. Polynesian people from Tahiti settled in the Cook Islands in the 6th century. The Portuguese captain, Pedro Fernandes de Queirós, made the first recorded European landing in the islands in the early 17th century, and well over a hundred years later, in the 18th century, the British navigator, Captain James Cook arrived, giving the islands their current name. Missionaries developed a written language, bringing schools and Christianity to the Cook Islands in the early 19th century. Cook Islands Māori, also known as Māori Kūki 'Āirani or Rarotongan, is the country's official language.
The Culture Division of the Cook Islands Government supports and preserves the country's national heritage. One of the popular traditional dances of the Cook Islands is the Ura, a sacred ritual usually performed by a female who moves her body to tell a story, accompanied by intense drumming by at least five drummers. The craft of the locals can be seen in dresses, sarongs, and jewellery crafted with local products, such as shells, and an important practice among women is tivaevae, a type of quilting. Typical cuisine consumed in the Cook Island is fresh seafood such as octopus or clams, lamb or suckling pig, and fresh fruit, especially coconut. Rugby union and bowling are popular sports, and the islands hosted the 1986 Pacific Cup and the 1998 Polynesia Cup. The House of Ariki (Are Ariki) offers dignity but limited power to the ariki, historical chiefs in the islands' social hierarchy.
