It happened in front of a crowd of more than 15, 000 at the Sir John Guise stadium this afternoon.
Trailing 13-6 at half time, the Hunters came back strongly to leave the Seagulls scoreless in the second 40 minutes.
The Hunters began their assault in the 55th minute of play when a penalty saw captain Israel Eliab opt to go for the two points.
The ball was given to kicker Ase Boas who converted to put his team within five points of the Seagulls lead.
Straight from the kick off, the Hunters raced back into Seagulls territory and created a gap for Stargroth Amean to score. Boas added the extras for the Hunters to take the lead for the first time in the game.
The Hunters were in again right from the restart through Oti Bland Tony who left the crowd screaming for more points.
With all the momentum going their way, the Hunters toyed with the Seagulls defence, scoring three more tries in the last 10 minutes.
Tries went to Kato Ottio, Willie Minoga and the final try went to Adam Korave who scored a minute out from full time.
