Henstock was in the action again as a bouncing ball fell nicely for him to score in the right corner. A successful conversion gave the visitors a 12-5 halftime lead.
There was stalemate for much of the second half as errors crept into the game, but with Aquinas looking increasingly likely to score, it was skipper and lock Callum Hoare who seized the initiative and bagged the try that gave Wood the chance to level the scores.
"You do not know how proud I am of this team," said Taylor. "We have worked so hard. I only came in here five weeks ago because they didn't have a coach.
"We've been so close to Western Heights, so close to other teams and just haven't finished it, but it's come together now ... [The players] have stepped up today and done some fantastic jobs. Andrew Norman, James Wood, they really stepped up today and the forwards. It was a fantastic team effort."
Otumoetai College 1st XV co-coaches Jamie Davis and Richard Brown both praised the Aquinas effort.
"The right team won because of their passion, dedication and application," said Brown.
With Otumoetai heading for next week's playoffs, Davis said he felt the loss could be helpful.
"We needed something to ground the team a little bit and this could be the catalyst for the team to say maybe we've got ahead of ourselves a little bit. This wasn't the performance we are capable of."
He said the main issues were poor execution and poor decision making.
In next weekend's semifinals, Otumoetai will travel to Opotiki College while Te Whare Kura o Mauao will play Western Heights High School in Rotorua.
