New Zealanders, also known colloquially as Kiwis, are the citizens, residents, and individuals associated with the country of New Zealand, sharing a common history, culture, and language (New Zealand English). People of various ethnicities and national origins are citizens of New Zealand, governed by its nationality law.
Originally composed solely of the indigenous Māori, the ethnic makeup of the population has been dominated since the 19th century by New Zealanders of European descent, mainly of English, Scottish, Welsh and Irish ancestry, with smaller percentages of other European and Middle Eastern ancestries such as Greek, Turkish, Italian and other groups such as Arab, German, Dutch, Scandinavian, South Slavic and Jewish, with Western European groups predominating. Today, the ethnic makeup of the New Zealand population is undergoing a process of change, with new waves of immigration, higher birth rates and increasing interracial marriage resulting in the New Zealand population of Māori, Asian, Pasifika and multiracial descent growing at a higher rate than those of solely European descent, with such groups projected to make up a larger proportion of the population in the future. New Zealand has an estimated resident population of around 5,324,700 (as of June 2025). Over one million New Zealanders recorded in the 2013 New Zealand census were born overseas, and by 2021 over a quarter of New Zealanders are estimated to be foreign born. Rapidly increasing ethnic groups vary from being well-established, such as Indians and Chinese, to nascent ones such as African New Zealanders.
