The Māori were the first people to reach New Zealand, followed by the early European settlers. Following colonisation, immigrants were predominantly from Britain, Ireland and Australia because of restrictive policies similar to the White Australia policy. There was also significant Dutch, Dalmatian, German, and Italian immigration, together with indirect European immigration through Australia, North America, South America and South Africa. Net migration increased after the Second World War; in the 1970s and 1980s policies on immigration were relaxed, and immigration from Asia was promoted. In 2009–10, an annual target of 45,000–50,000 permanent residence approvals was set by the New Zealand Immigration Service—more than one new migrant for every 100 New Zealand residents. In the 2018 census, 27.4% of people counted were not born in New Zealand, up from 25.2% in the 2013 census. Over half (52.4%) of New Zealand's overseas-born population lives in the Auckland Region. The United Kingdom remains the largest source of New Zealand's immigrant population, with around a quarter of all overseas-born New Zealanders born there; other major sources of New Zealand's overseas-born population are China, India, Australia, South Africa, Fiji and Samoa. The number of fee-paying international students increased sharply in the late 1990s, with more than 20,000 studying in public tertiary institutions in 2002.
