National Provincial Championship (2006–present)

The National Provincial Championship, often simply called the NPC, is an annual round-robin rugby union competition in men's domestic New Zealand rugby. First played during the 2006 season, it is the second highest level of competition in New Zealand alongside the Ranfurly Shield. It is organised by New Zealand Rugby (NZR) and since 2021, it has been known as the Bunnings NPC after its headline sponsor. A concurrent women's tournament is also held, the Farah Palmer Cup.

Following the 2005 season the league was restructured into a two-tier competition. The National Provincial Championship would include professional and semi-professional players, and consist of the top fourteen financial and best performing regional teams. For sponsorship reasons it was rebranded as the Air New Zealand Cup. The remaining teams would form a breakaway amateur competition known as the Heartland Championship.

Twenty-nine teams have competed since the inception of the competition in 1976. Auckland are historically the most successful union with seventeen titles and Canterbury is the most successful team during the professional-era, having won nine from eleven finals. Eight other teams have won titles from both periods: Wellington (5), Waikato (3), Otago (2), Taranaki (2), Tasman (2), Bay of Plenty (1), Counties Manukau (1) and Manawatu (1).
