Society and culture
New Zealand is culturally and linguistically(in terms of language) part of Polynesia(part of Oceania including Easter Island, Hawaii, New Zealand, Samoa, Tahiti, and Tonga). Much of contemporary(modern, of the present age) New Zealand culture derives from British roots. It is made up of significant(having a noticeable or major effect, notable) influences from American, Australian and Māori cultures, along with those of other European and Asian cultures. Large festivals in celebration of Diwali and Chinese New Year are held in several of the larger centres. The world's largest Polynesian festival, Pasifika, is an annual event in Auckland.
Population
New Zealand has a population of about 4.3 million, of which approximately 78% identify with European ethnic groups. Most European New Zealanders are of British and Irish ancestry(lineage, or those who compose the line of natural descent), although there has been significant Dutch, Dalmatian, Italian, and German immigration together with indirect European immigration through Australia, North America, South America and South Africa. Indigenous(native to a land or region) Māori people are the largest non-European ethnic group, accounting for 14.6% of the population in the 2006 Census.
Language
Until 1987, English was New Zealand's only official language, and remains predominant(the most common or widespread; prevalent) in most settings. Māori became an official language in 1987 and New Zealand Sign Language in 2006. The two official spoken languages, English and Māori, are also the most widely used; English is spoken by 98% of the population and Māori by 4.1%. Samoan is the most widely spoken non-official language (2.3%), followed by French, Hindi, Yue and Northern Chinese.
Religion
According to the 2006 census, Christianity is the predominant religion in New Zealand, held by 55.6% of the population. Another 34.7% indicated that they had no religion, and around 4% affiliated(to associate with; to become a member of a group) with other religions. There are also significant numbers who identify themselves with Pentecostal and Baptist churches and with the LDS (Mormon) church. According to census figures, other significant minority religions include Hinduism, Buddhism, and Islam.
