Mate Ma'a Tonga became the first second tier nation to defeat a tier one side, with a 28-22 win sealing top spot in the group.
Last week's shock 28-22 victory over the Kiwis saw Tonga finish ahead of New Zealand, setting up a clash with Lebanon for a spot in the tournament semi-finals.
Speaking to media versatile back, David Fusitu'a spoke about the intensity of the match.
"It was crazy, I know the boys really enjoyed it," he said.
"The effort the boys put in there... they did it for each other, it really showed out there."
