A new report into the value of kapa haka is calling for more dedicated research about its economic, social and cultural significance to be launched.
Nga Hua a Tane Rore, the Benefits of Kapa Haka, was carried out by Waikato University's Te Kotahi Research Institute, which interviewed about 50 people involved in the art.
The research explored how kapa haka contributes to New Zealand's society, and suggests that the national competition, Te Matatini, creates an economic boom for places where it is held.
Last year, tens of thousands of people poured in to Rotorua for the event, which contributed about $7 million through accommodation and hospitality.
An arts policy adviser at the Ministry for Culture and Heritage, Marie Brown, said the new information with personal stories are good, but more robust studies including longitudinal research are needed.
Ms Brown said they would quantify the value that kapa haka has across education, health, social outcomes, national identity and its value overseas.
The report was prepared for the Ministry for Culture and Heritage and Te Matatini national board.
