The French Territory has won 42 gold medals after the first six days of competition and more than 50 silver and bronze, with host nation Samoa the nearest challenger with 26 gold medals while Tahiti have 21.
Another six first place finishes on the final night of swimming action brought New Caledonia's total haul in the pool to 25 gold, 11 silver and 13 bronze medals.
Swimming Team Manager Cyril Huet said it's an even bigger haul than they managed in Port Moresby four years ago.
"We are very happy and the team is very unique," he said. "We win the Games because it's an objective we want to win the Games, but behind you you have the team of Fiji it's a very good team too and finished No.2 (in swimming) and is very good. To have competition with Fiji, Samoa, Tahiti, Cooks, it's very good competition."
"All the team is high level. The girls win 12 gold medals, the boys win 11 gold medals. It's a group, it's a unique group. Not one swimmer is better - it's all the group, I think. We want all the time to work all together," he said.
