Māori language influence on New Zealand English

During the 19th century, New Zealand English gained many loanwords from the Māori language. The use of Māori words in New Zealand English has increased since the 1990s, and English-language publications increasingly use macrons to indicate long vowels. Māori words are usually not italicised in New Zealand English, and most publications follow the Māori-language convention of the same word for singular and plural (e.g. one kākāpō, three kākāpō).
