The Stallions fought their way back into the contest early in the second half and cut the deficit to two points.
The game ebbed and flowed and, at 36-32 to the Falcons, either team might have come away with the win.
In the end, the Falcons claimed the victory by 10 points.
Seeka Falcons coach George Tanirau said his team were forced to do a lot of defending.
“We were expecting a big match like that,” he said.
Tanirau said his side sometimes tried to do too much with the ball and handed over possession.
He said Falcons wing Jermaine Cooper and standoff Kingston Kennedy had standout performances and “saved us in crucial moments” on defence.
“The Stallions’ fitness and their youth really kept them in the game.”
Stallions captain Dylan Williams said his team had the wind in the second half and used their speed and footwork.
Williams said new fullback Rawiri Barnsley was hard to contain.
He was pleased with the effort shown by his side but their opponents capitalised on mistakes.
