World Rugby unveiled its Pacific Nations Cup format today, announcing that the revamped six-team tournament would take place over five weekends from August 23 to September 21.

The new format is intended to increase competitiveness by creating a Six Nations or Rugby Championship-like tournament for tier-two countries ahead of the 2027 World Cup, which has been expanded to 24 teams from 20.

Each team will play at least three matches, with Fiji, Samoa and Tonga making up Pool A, and the top two teams from each pool advancing to the semi-finals.

The final series of this year’s competition will be held in Japan, with the U.S. hosting the final in alternate years.

The teams in each pool play each other in home or away fixtures in a round-robin format, with the pools themselves created with an eye on reducing long-distance travel and the competition’s carbon emissions.
