The Ranfurly Shield, colloquially known as the Log o' Wood, is perhaps the most prestigious trophy in New Zealand's domestic rugby union competition. 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. Holders Six different unions held the Ranfurly Shield between 1930 and 1939.
