Nine Te Arawa teams out of the 75 teams will be taking part in the tournament, which was a chance for players to represent their iwi she said.
Having the tournament was a big coup for Rotorua, she said.
"We can't get national games here because of the facilities. You need to have power available in the middle of the fields and we have rented the equipment to do that," she said.
The tournament is family friendly and will have a village with bouncy castles, and stalls selling food and clothing.
Many of the games will feature the "best of the best" of Maori touch, she said.
"The men's open is the most competitive grade and the under 21 boys always have good games," she said.
The public are welcome to go and watch the tournament, including the pohiri on Saturday morning at 9am, and the whakangahau (function) on Saturday night.
