A17. Some people simply do notadd a plural suffix -s when the word Maori is used in a plural context in written English, i.e., they use the word according to rules of Maori language. It is interesting to see this usage appearing in New Zealand government publications and it may be become a feature of New Zealand English. Others follow style guides or publishing house rules which insist that the plural suffix -s be added when the word Maori is used in plural context. Last modified: 22 October 2007.
