Whakarewarewa captain and Steamers second-five Doug Edwards believes the extra teams are important for developing rugby and keeping players in the regions.
"I grew up watching Waikite when they were at their peak and they were the best team in the Bay," Edwards said.
"When they played us they brought an intensity for 60 minutes that was a quality I enjoyed to watch; even though I was receiving it. It is really up to them how they manage to produce that game in, game out."
Opotiki will be strong in the forwards as always but new player Sam Carran says rugby generally in Eastern Bay is in better shape than it has been for years.
"Without a doubt we are going for a playoff spot this season. We want to prove it these first three weeks against three good sides in Tauranga Sports [home]; Te Puke and Mount Maunganui. We need to win one of those.
"We know that we are a really good team this year and have put together some really good performances."
Mount Maunganui Sports, Tauranga Sports, Te Puke Sports and Greerton Marist look most likely of the Western Bay clubs to be pushing for semifinal spots.
Tomorrow's opening round includes two local derbies certain to spark the passions. Mount Maunganui Sports host Te Puke Sports at Blake Park while Rangataua travel across town to take on Te Puna.
