The traditional name for New Zealand is 'Aotearoa,' meaning 'land of the long white cloud.' It is the southwestern most part of the Polynesian triangle. The indigenous people of Aotearoa are the Maori and the traditional greeting is 'kia ora.' Individuals are often greeted by pressing one's nose and forehead with the other person in a greeting known as the 'hongi.' This is to symbolize the sharing of one's breath or life force. Aotearoa is comprised of many different tribes, or 'iwi.' Each of these have several distinct features, including a marae (meeting house), river, 'waka' or canoe, mountain, 'tangata' or chief, among others. New Zealand's government is part of the Commonwealth of Nations.
