The team won their third Coupe de Calédonie against close rivals FC Ferrand 2-1 in early December which gave them the Cup-League double for the second itme.
The side, led by national team coach William Bret, have been on an upward trajectory since their first double in 2014.
It took just one minute for Olympique to open the scoring against FC Ferrand in the Coupe de Calédonie final courtesy of a Ludovic Boit strike.
The lead was extended when Wahid Ben Ameur added a second in the 38th minute.
Ferrand adopted the flying keeper approach in the second period with keeper Arnaud Llambrich, who managed to score a late consolation goal in the 39th minute.
With the 2-1 victory Olympique ensured they would once again claim the league and cup double, as well as extend their winning streak to 34 matches on the trot, and 46 matches undefeated.
