An official after-match buffet dinner will conclude the weekend's festivities, to be held at Kaitaia's Te Ahu Centre at 4.30pm.
Mangonui Rugby Sub-Union chairman Marty Yuretich said he was excited for the community to get in on the celebrations and wanted to thank them for their ongoing support.
"Our club is really excited about celebrating our 100-year birthday and want to say thank you to all the players and supporters who make the games happen," he said.
"We're looking forward to growing rugby union long into the future and getting the community together to celebrate what has been a major part of the Far North and its history.
"On Saturday people can look forward to some great games and seeing the contributions from the little kids being ball boys or the Mangonui refs, as well as some young talent who are coming back from Auckland and Whangārei to play on the day."
