All four nations that participated picked primarily Auckland based players. The Cook Islands and Tonga also played in the Papua New Guinea 50th Anniversary Tournament played during the same month. Papua New Guinea, Fiji and Samoa declined an invitation to compete. All four nations played each other once with the top nation crowned winners. The last match between American Samoa and Tonga turned out to be, effectively, a final after both won their first two games. Tonga won that match to win the tournament.
