New Zealand has a rich and fascinating history, reflecting a unique mix of Māori and European culture. While New Zealand is still heavily influenced by its colonial heritage, the country now has its own strong sense of identity. While still a member of the British Commonwealth, and maintaining close, friendly relations with the USA, New Zealand now has a far more independent trading and foreign policy. Since the mid-1980s, New Zealand has been a nuclear-free zone, with its armed forces primarily focused on peacekeeping in the Pacific region.
