Auckland (2014–2017) Two national women's teams compete in one section of the tournament and sixteen NRL club men's teams compete in the other. Each of the men's squad must include at least 12 of their top 25 players in their squad, and at least one marquee player. The winner of the men's tournament received
AUD$500,000 with a total prize pool of AUD$2,250,000. In the first four editions, the competition has had eight different finalists and four different winners, though the 2016 title was later stripped from the Parramatta Eels for breaching the salary cap. Since 2015 the
Kiwiferns and the
Jillaroos also competed in a three-game series, with the Kiwiferns winning the series 2-1. These games are played during the final stages of the men's tournament and allow the male players more of a break between their games while providing a broader tournament. Also in 2015, the pools were given traditional Maori names that were chosen by a public vote and were:
Rangitoto,
Waiheke,
Piha and
Hunua Ranges.
Perth (2020) The women's teams were
NRL Women's Premiership sides instead of national teams.
Series Cancellations (2021–2024) The 2021 series was cancelled entirely, not due to the
COVID-19 pandemic in Australia, but due to an overly-crowded preseason schedule. When the 2022 Fixtures list was released by the NRL, it included no mention of the
World Club Challenge or NRL Nines competitions. The
World Club Challenge did make its return in 2023, and again in 2024, but the NRL Nines competition was absent for both years. ==Rules==
