They were fortunate, however, not to be reduced to 14 players themselves halfway through the opening spell, after a dangerous tackle prevented Te Puke fullback Elliot Hagen from scoring and injured him out of the game.
Across town at the Tauranga Domain, second-placed qualifiers and defending champions Tauranga Sports knew they were in for a tough battle against Rotorua's Whakarewarewa - and that is exactly what they got.
Whakarewarewa travelled over with a good number of noisy supporters and won an intensely absorbing clash by 18-17.
Tauranga Sports first-five Paul Morris had a chance to win it with a late sideline conversion but his kick slipped past the upright.
The Premier final between Mount Maunganui and Whakarewarewa is at 2.45pm this Saturday at the Tauranga Domain, preceded by the development final between Greerton Marist and Tauranga Sports at 1pm.
