The Ranfurly Shield, colloquially known as the Log o' Wood, is arguably the most prestigious trophy in New Zealand's domestic rugby union competition.[citation needed][dubious – discuss] First played for in 1904, the Ranfurly Shield is based on a challenge system, rather than a league or knockout competition as with most football trophies. The holding union must defend the Shield in challenge matches, and if a challenger defeats them, they become the new holder of the Shield.
