Taranaki bounced back through excellent vision from wing Waisake Naholo that allowed fullback Jayson Potroz to score his second try in as many weeks. The try was converted by Potroz himself but that was the only time the Bulls got close to the home side.
Hawke's Bay showed incredible patience leading up to Emerson's second try and soon after second five-eighth Danny Toala sliced through the defence. Hawke's Bay took a strong 21-7 lead into the break.
During the try scoring, Taranaki suffered a blow as hooker Ricky Riccitelli left the field with a calf strain midway through the first half. That bought Bradley Slater onto the field who played an impressive role in his fifth appearance for the Bulls.
After halftime, Taranaki started well that included a penalty kick to Perofeta, but it all went downhill from there.
Referee Nick Hogan, who blew 35 penalties in the match, ran out of patience as two players were sent to the sin-bin within minutes of each other. First, lock Leighton Price was shown yellow, followed by flanker Heiden Bedwell-Curtis in the following movement, who gave away a penalty try in the process.
Toala scored his second try, while Bedwell-Curtis made the score look a little more respectable dotting down under the posts before fulltime.
Speaking after the match, Taranaki vice-captain Teihorangi Walden credited Hawkes Bay for their performance but acknowledged his side's discipline let them down.
"The boys worked really hard this week on defence and we can't afford to give away penalties. We will connect up, stay tight and move forward into the competition."
