The tournament is in memory of Nate Miller, who, at the age of 28, died in a forestry accident last year.
Miller was a player who had a wealth of mana in Gisborne's rugby league scene.
A post on Gisborne's rugby league Facebook group said Miller had gained respect on and off the field for the way he carried himself.
“You were a beast! On behalf of the Paikea Whalers, I'd like to thank you for the memories, most of them watching you running in for another try,” the post said.
His mother, Karen Black, said it was overwhelming to see the love and support from the rugby league community.
“We just didn't know how many hearts he touched. He was the type of guy that would give you his last dollar.”
His younger brother, Harlee Kohn, will take the field playing for the Seeka Falcons.
Karen Black said Kohn was “really proud” to be taking the field this weekend in memory of Nate.
Tournament organiser Ally Tamihere said Nate was an “amazing” player on and off the field.
“Nate was NRL material; he had the opportunity and the talent.”
She said the tournament would become an annual feature to remember someone who was a vibrant member of the local rugby league community.
“We couldn't do this without his family's blessing.”
Ally Tamihere said she organised the tournament out of the respect and aroha she had for Nate and his family, particularly his daughter, Rongokino.
Karen Black said he called her his little princess, and she was growing up to be just like him — athletic and smart.
The day will start with a karakia at 10.45am. Games will start at 11am and the final is expected to begin at 2.30pm.
