BOPRU operations manager Neil Alton said clubs were right behind the idea.
"From the success and unique format of last year's 10-a-side colts competition, clubs have gained traction with this age group and have realised the importance the colts competition has. It provides an important link for school leavers before stepping into senior rugby."
Eastern Bay of Plenty rugby manager Mark Seymour said: "What makes this competition engaging is that it caters for guys who have just left school and are wanting to get involved but are not quite ready for senior footy. The competition suites people who are working and/or have busy lifestyles too."
A pre-season tournament is being held this weekend at Mt Maunganui College. The official start date of the 2016 Baywide Colts and U85kg competition is Saturday, April 3. The draw will be released the week starting March 31.
