The two official languages of New Zealand are Māori and New Zealand Sign Language. However, English is the predominant language and a de facto official language of New Zealand, with almost the entire population speaking it either as native speakers or proficiently as a second language. The New Zealand English dialect is most similar to Australian English in pronunciation, with some key differences. Māori, the language of the indigenous Māori people, was made the first de jure official language in 1987. New Zealand Sign Language (NZSL) has been an official language since 2006. Many other languages are used by New Zealands minority ethnic communities. According to the 2013 Census, after English and Te Reo Māori, Samoan was the most widely spoken language, with 86,403 people (2 per cent of the population) able to speak it. The most spoken languages in New Zealand are English and Te Reo Māori, with Samoan, Chinese, and Hindi completing the top five.
