An Auckland professor and bilingualism researcher is encouraging more parents to consider bilingual education for their children.
Professor Stephen May said there were many advantages to growing up bilingual and more parents should consider Maori-medium education.
"Bilingual and immersion programmes, like Maori-medium education, are highly effective but there's a lot of scaremongering out there about them, and some widely held and very entrenched negative attitudes about bilingualism and bilingual education."
The professor of education at the University of Auckland said he grew up monolingual in Christchurch, where he had had few opportunities to learn other languages.
Learning a new language was more difficult as an adult, May said.
