Assistant coach Aaron Sutherland says a handful of players are backing up from last year's winning team.
For players up to Year 8, he says Year 7 players are normally included in squads to give some continuity.
"This year we have about half a dozen Year 7 [students]. I suppose they are fringe players this year but will step into the leadership roles in their Year 8 year."
Those who are backing up this year include Wyndham Patuawa, who went on to be selected for the Bay of Plenty Roller Mills team, Rico Kelly, Kerry O'Reilly and Aidan Spratley.
Two of the stars from last year's title-winning team, Fijians Nacani Batidravu and Waisake Salabiau, are no longer eligible. However, Maloni Bole and Malakai Cama, who are at Te Puke Intermediate School on rugby scholarships, are in the side this year.
"The Fijian boys are good quality players, but the local boys are standing out as much or more this year," Sutherland says.
"Everybody's contributing right across the 22 — that's a strength we've got, probably more so than any individuals. And they are good kids as well as good players."
He says while the current squad is aware of it, he doesn't think being defending champions will hamstring the players.
Aidan Kuka, coach of last year's second-placed squad Tauranga West, said his team was going into the tournament with a relatively young squad who have had a good build-up ahead of today.
"We've got a lot of younger players this year, so we're looking to possibly build for next year," Kuka said.
He says there are two experienced members on his team who the younger players will be guiding the team during the competition - Captain Kash farmer leading his team at number 12, and Paora Elder at number 4.
"Those two will be our go-to boys during the tournament."
Kuka believes Te Puke will be in the finals and his side will work hard to get there.
"We'll be working hard to put ourselves there," he said.
Tauranga West leave for Rotorua this morning and is looking forward to the tournament he sees as one with "a lot of mana", something primary school pupils set their sights towards and a stepping stone for future representative players.
Bay of Plenty Primary Schools president Wayne Fell said the support from the Wasps Rugby Football Club was instrumental to the successful delivering of this week's tournament.
Wasps Rugby Football Club president Craig McCord said they were proud to play their part in the development of the Bay of Plenty's emerging talent.
"We are proud to be associated with Tai Mitchell Tournament and the contribution it makes in the development of our emerging sporting talent throughout the Bay of Plenty," McCord said.
■ The original Tai Mitchell Shield was presented by Mr Henry Taiporutu Mitchell in 1938, for competition among the primary school teams representing Bay of Plenty rugby sub-unions. The tournament doubles as a trial for the Bay of Plenty Roller Mills team, which will represent the province at the northern regional tournament.
