The Ranfurly Shield, colloquially known as the Log o' Wood, is a trophy in New Zealand's domestic rugby union competition. First played for in 1904, the Shield is based on a challenge system. The holding union must defend the shield in challenge matches, which are usually played at the shield holder's home venue, and if the challenger is successful in their challenge they will become the new holder of the Shield. There is a tradition for the first challenges of a new rugby season to be played against smaller associations from the Heartland Championship.

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.
