Researchers believe they could break down cultural barriers by studying differences in the way Maori and Pakeha communicate. But critics question why taxpayer money should be spent on this when the two cultures are already perfectly capable of relating to each other.

A team at the newly formed New Zealand Institute of Language at Canterbury University has done a pilot study comparing facial expression, gesture and posture by both Maori and Pakeha, and wants government funding for a larger study.

It is hoped the research findings will give greater insight and help combat prejudice. But a former MP and social commentator described it as a waste of money.
