Cook Islands territory profile

The 15 volcanic islands and coral atolls of the Cook Islands are scattered over 770,000 square miles of the South Pacific, between American Samoa to the west and French Polynesia to the east.

A former British protectorate which became self-governing in 1965, the territory is now in free association with New Zealand.

Its economy centres on tourism; the territory's natural assets include fine beaches and volcanic mountains.

Named after Captain Cook, who explored them in 1773, the islands were once autonomous, home to tribes of mixed Polynesian ancestry.

Governments still seek advice on matters of culture, custom and land ownership from a council of hereditary leaders known as the House of Ariki.

More than twice as many native Cook Islanders live in New Zealand than live in the islands themselves. Most of them have left in search of a brighter economic future. As New Zealand citizens they can also live in Australia.

Black pearls are the chief export. Agriculture, the sale of fishing licences to foreign fleets and offshore finance are also key revenue earners.

Head of state: Queen Elizabeth II, represented by a governor

Prime Minister: Henry Puna

Prime Minister Puna is a pearl farmer

Lawyer and pearl farmer Henry Puna took office in December 2010 after his Cook Islands Party won a comfortable majority in elections.

The Cook Islands Party unseated the Democratic Party which had dominated politics on the islands for the past decade.

Mr Puna's party won a two-thirds majority of the 24 seats in parliament.

Before the elections he was quoted as saying he planned to pay a $770 "baby bonus" to the mother of each child born in the Cook Islands to try reverse a steady decline in population caused by migration to New Zealand.

His government retained a narrow majority in the 2014 parliamentary elections.

Mr Puna studied law in Auckland University and the University of Tasmania before returning to practice law in the Cook Islands.

The main radio and TV stations are operated by the privately-owned Pitt Media Group, which also publishes weekly newspapers.

Radio Australia broadcasts on FM on Rarotonga.
