Before his departure for Brasilia Mr Brown said he had been asked to advise on how traditional Maori games were run in New Zealand. A crucial part of the preparation was the tatu, whereby competing tribes met beforehand to come up with an agreed set of rules.
The club had also been asked to send a delegation to Palmas for the October 20-November 1 games, where they would demonstrate 11 traditional Maori games, including ki-o-rahi, ti-uru (a ball game played on a court), hupara (high jump using stumps) and wera-te-paatu (a test of balance on a rock wall).
So far 14 club members had put up their hands to take part in a great chance to link up with traditional sports players from around the world.
"This is huge. This is the Olympics of traditional games," Mr Brown said.
Tane Waetford (Ngatiwai/Ngati Hine), who is now the deputy Head of Mission at the New Zealand Embassy in Brasilia, said the games organisers had reached out to a number of countries, including New Zealand, to attend the technical meeting.
"Through the Brazilian Embassy in Wellington they were able to identify Harko, given his experience in traditional games. We'll be pleased to have him here to provide input into the games from a New Zealand and Maori perspective," Mr Waetford said.
New Zealand's role in the games, which would begin with a three-day cultural festival, would be clearer after the meeting, he added.
