New Zealand English [SEP] Māori influence
Many local everyday words have been borrowed from the Māori language, including words for local flora, fauna, place names and the natural environment. The dominant influence of Māori on New Zealand English is lexical. A 1999 estimate based on the Wellington corpora of written and spoken New Zealand English put the proportion of words of Māori origin at approximately 0.6%, mostly place and personal names. The everyday use of Māori words, usually colloquial, occurs most prominently among youth, young adults and Māori populations. Examples are "kia ora" ("hello"), "nau mai" ("welcome"), and "kai" ("food").
