The Hunters were trailing 14-8 at the break and edged out last year's Intrust Super Cup winners in the last three minutes of the match.
The Hunters hit four minutes into the second half through a solo effort from fullback Bland Abavu who shrugged off five defenders to score near the posts.
The score was levelled at 14-14 thanks to the boot of Ase Boas.
From here, the Hunters muscled up in defence determined not to let the Jets back into the game.
Boas put the home side in front for the first time kicking a penalty in the 55th minute of play.
But the Jets were still in the game 10 minutes later after Jaydan Lipp successfully converted a penalty.
The win was sealed for the Hunters when Boas kicked through the winning points.
From over 30 metres out, Boas took his time and slotted the ball between the posts to leave the 6,000 plus supporters screaming in celebration.
Justin Olam was named man of the match while Brandy Peter and Adam Korave had extra reasons to celebrate both playing their 50th game.
