The Tigers were on the board inside the first ten minutes through fullback Joe Joshua.
The visitors registered their first points when they opted to kick for goal.
They soon found the try line just minutes later when Sikeli Qauqau reached over to slam the ball down.
A successful conversion put the Aviators in front by four points.
But they let the Tigers back in when lazy defence allowed Mafu Kales to sneak in a four pointer.
The Tigers dominated the last ten minutes running in two more tries to Junior Rop and Joshua to take them to a 20-8 lead going into the sheds.
There was a flurry of tries from both sides in the second term.
Joshua grabbed his third of the match to get things going.
But it was far from over.
The boys from Fiji proved they had plenty of fight in them striking twice to reduce the deficit with the score now at 26-12 with less than 20 minutes on the clock.
Stanley Tepend's men dished out the same dose to the opposition sending in Tiger Emeri and Noel Joel to seal victory and win the Tigers their second consecutive Melanesian Cup.
