Hunt found his way to the line in the 54th minute as the Dragons opened up a 14-point lead with the breeze at their backs.
In the 62nd minute Hunt delivered a superb long ball for Mikaele Ravalawa to steamroll defenders and score out wide as the home side put the result beyond doubt.

With eight minutes to play the Dolphins hit back with a spectacular long-range try featuring great work by Isaako and finished off by Hamiso Tabuai-Fidow, who now has six tries for the season.
Tyrell Sloan then exploded into a hole from 40 metres out and got the ball down for the Dragons' seventh try despite Tabuai-Fidow's best efforts to deny him.
