Tauranga's Geoff Booth said the commitment from his team was outstanding.
"Today we spoke about 'explode with urgency' and you could not question that. They were urgent on defence and that is what got them through, especially in that second half," Booth said.
"We built pressure really well and finished well. I love seeing rugby where wingers score tries and today we had three tries out on the wings which were whole team tries."
Te Puke coach Rameka Pohipi says his team worked so hard to secure a final's place.
"That win over Rotorua was probably the highlight, just to see the change in them and to see them step up to the mark and finally think they can do it," Pohipi said.
"But I think they were a little bit overawed by the occasion today and they were not there in the first half. They came to the party in the second half but it was a bit too late then."
