"We managed to pull it out of the fire," Whanganui Maori coach Dennis Tucker said. "It was a great game."
But while he was pleased with the effort to come back, Tucker thought his side should have scored more early on.
"Just last minute dropping the ball, that was slowing things down. But the guys played really well."
Tucker said it was a game played in good spirit and hoped it would become an annual fixture with some sort of taonga to play for.
"It's good rugby, good flowing rugby and good for the crowd," he said.
"The guys all know each other. There's no trophy yet but bragging rights were definitely up for grabs."
Samoans coach Ace Malo said his side might have run out of petrol in the tank when they let the Maori back in.
"Just mistakes cost us in the end, we missed a couple of kicks. But I think they were favourites so I'm really happy.
"We got everyone on the field and we should've won it."
The match was the last for both sides this season.
