The IRB Pacific Nations Cup is an International round-robin competition comprising the test teams of Fiji, Samoa, Tonga and Japan.  The Junior All Blacks - who in 2008 were replaced by the New Zealand Maori - and Australia A no longer participate.  

Like the IRB Pacific Rugby Cup, the IRB Pacific Nations Cup is a key component of the IRB’s Strategic Investment initiative and is designed to provide the Pacific Island Nations and Japan with regular high level international competition.  In 2013 the IRB Pacific Nations Cup has been expanded to include USA and Canada in a welcome development to what is becoming an increasingly popular tournament.  The addition of these two Unions is a boost for the growth of rugby and will expose more people to the unique style of rugby played in the Oceania Region.  Importantly, it will contribute specifically to an increase in Test matches for all Member Unions and build towards a more competitive Rugby World Cup.

In 2013 IRB Pacific Nations Cup matches will be hosted in Japan, Fiji, Canada and USA.  All five teams will travel to Japan for the final two rounds of the Tournament.
