Bay of Plenty Rugby chief executive, Mike Rogers, said promoting players to the next level was what they hope to achieve with all of the Steamers players.
"Ziggy has always had that physical prowess and the ability but this year he has really worked hard with our strength and conditioning trainers,' Rogers said. "That is demonstrated by what he has achieved in the ITM Cup so for him to go on and get a Super Rugby contract, through good performances at the ITM Cup level, is a perfect outcome for us.
"Chase made a really strong contribution and again it demonstrates opportunity. He has taken full advantage of it, coming up from Wellington, and again highlights why a guy like Mitch Karpik and others have signed for the Bay. Chase has set that platform to show that this is a good environment for people to be successful in.
"It is another really positive outcome for us to show this is a good place to be and we can help individuals get to the next level."
Chiefs head coach Dave Rennie believes they have assembled a squad with a good blend of enthusiastic debutants and experience, with 12 current and former All Blacks in the team.
"The 14 new faces, our highest turnover since 2012 when we had 16, gives us an exciting blend of youth and experience and excellent depth throughout.
"The new competition structure will be challenging with more travel, but being the first team to play in Buenos Aires will be an amazing occasion," said Rennie.
There are 26 players returning to the Chiefs including former All Black and Rugby World Cup hero Stephen Donald.
Donald has played 85 matches for the Chiefs, last appearing for the side in 2011.
