But the Steamers did not make the one-man advantage pay on the scoreboard and restored to 15 players, Tasman laid siege in the Steamers 22. But the Steamers survived with some great defence led by Bardoul and cleared the danger.
Just before the break Tasman finally made their territorial dominance pay when winger Mitchell Scott skipped past Leroy van Dam to score in the corner. Banks converted from touch for a 14-3 lead at the break.
Tasman kicked a penalty in the opening minute of the second spell before the Steamers scored one of the best team tries of the season so far finished off by Hohneck. 17-10.
The Bay hoed into their work and enjoyed some good spells on attack. Banks kicked a penalty for a 10 point gap but Evemy missed from a handy angle after a later tackle on Steamers replacement winger Whaimotu Craft-Chemis.
A minute later Chase Tiatia made a slashing break but his pass infield was spilled by Ziggy Fisi'ihoi with the line open as the Steamers put real pressure on the Makos.
Dan Hollinshead replaced Evemy and kicked a penalty to reduce the gap to seven with 15 minutes to play, before Kieron Fonotia crossed for a try for Tasman to essentially end the contest.
Tiatia had a late chance to grab a bonus point for the Steamers but lost the ball in a heavy tackle. Peter Samu scored right on fulltime to give Tasman a bonus point.
Tasman 34 (Liam Squire, Mitchell Scott, Kieron Fonotia, Peter Samu tries; Marty Banks 4 cons, 2 pen)
Bay of Plenty 13 (Zac Hohneck try; Nick Evemy con, pen; Dan Hollinshead pen)
