Each team played each other once in their respective conferences, with no interconference matches. Four points were awarded for a win, two points for a draw and one point for a bonus point; the bonus point being awarded should a team score four or more tries in a match, or for a loss by seven points or less. The winner of each conferences was the team with the most log points, with tiebreakers being the head to-head results between teams equal on log points, followed points difference for-and-against. As the three-week tournament coincided with the three-week June international window, players were able to be released from their clubs for their national teams. When a team was not in action in either conference, they played host to a touring Tier 1 nation from Europe. In Round 1, the United States hosted Scotland, while Fiji hosted Italy. In Round 2, Canada played Scotland, and Samoa played Italy. In Round 3, Japan hosted Italy and Tonga played a Pacific Barbarians side. The full match schedule was announced on 9 April 2014.
Fijian winger, Sireli Bobo became the oldest player ever to represent Fiji when he ran onto the field at 38 years and 137 days old.
