A groin strain robbed the Taniwha of Ash Moeke and without his kicking abilities and field direction, the home side struggled to score in the first spell.
Tane Takulua capitalised on his first start and blitzed the defence from a set-piece to score the opening try of the match.
The lead was brief however, and Taranaki's Frazier Climo drilled three first-half penalties along with the conversion of Kurt Baker's try, as the visitors finally broached the overworked Taniwha defence, to lead 16-7 at the break.
Taranaki continued to add to the lead before Rhyan Caine put Rene Ranger into a gap with his first touch of the ball to narrow the deficit to 17-22. Climo was then driven over the line to put Taranaki ahead 29-17 before the Taniwha finally started hitting their straps.
Orene Ai'i strained his groin. Carpenter moved in to first receiver and with six minutes to go replacement winger Dan Caprice scored.
