Six per cent of Maori in Australia speak te reo at home, compared with 25 per cent in 1986.
While many adults were enthusiastic about their language, there were few opportunities to speak and learn te reo. Maori and Dutch were among the languages least well retained among immigrants, while Lebanese Arabic was one of the best retained languages.
Among Maori speakers working in Australia were 140 te reo-speaking teachers.
Another problem faced New Zealand children from total immersion schools, who were still learning English but did not always get the help needed in Australia. Not all states provided tuition in English to New Zealanders as they did for children from other countries, Mr Hamer said.
