Four sides hail from the Central Districts catchment - Taranaki, Horowhenua-Kapiti, Hastings and Napier - and one from Wellington (North City).
"To enable us to have a final on Thursday, all 10 teams are in one draw so the top two teams after three rounds will play in the final on Thursday."
Napier and Hastings are flying the Hawke's Bay flag so, as a region, they have a 24-boy squad.
Findlay said it offered a representative age-group platform in its pilot year.
"By next year, we want to have 16 teams," he said, adding with the impending ICC World Cup from next month and international fixtures it took some juggling to get the primary/intermediate tourney off the ground this summer.
"It'll be played in Hawke's Bay at Nelson Park, which isn't just a premier venue here but in New Zealand."
The plan is to have four rep teams each from each major association of CD, ND, Wellington and Auckland.
"They'll score 100 runs here and there'll be no retirements, and bowlers will take fivers in the next four days," Findlay said of the games that start at midday.
