The most capped player is Culum Retalick with 92 games in the blue and yellow stripes.
The new players selected in the Steamers squad, including four other international sevens players in Joe Webber, Regan Ware, Isaac Te Aute and Hugh Blake, will be expected to make their Mitre 10 Cup debut this season.
Ten of the twelve Baywide Premier club sides are represented within the 37-man squad.
"This team represents our region. The quality of club rugby has improved, and as a result, we have a competition that's going down to the wire and brought a lot of excitement back to our club scene," McMillan said.
"The by-product of that is more players have been given an opportunity to shine, and this is reflected in the final squad.
"The team understand the demands and challenges ahead but have prepared accordingly and are ready to meet those challenges head on.
"We are not a team of household names but are determined to create a legacy of success, bring some mana back to the jersey, and earn the respect of our supporters and stakeholders by playing a brand of rugby synonymous with the Bay of Plenty."
Bay of Plenty Rugby CEO Mike Rogers says the Mitre 10 Cup is the toughest provincial rugby competition in the world.
"Every year it throws up some amazing new young talent. The tradition and pride associated with representing your community is hugely important to everyone involved," he said.
"The Bay of Plenty is a fantastic region and we are determined to show the rest of the country how proud we are of the Bay."
