John Rutherford "Jock" Butterfield was a New Zealand rugby league footballer of the 1950s and 60s who has been named amongst the finest that country produced during the 20th century. A New Zealand international representative forward, he played his club football in various places in New Zealand, New South Wales and Queensland. Butterfield held the record for most test caps for the New Zealand national team until overtaken by Gary Freeman. In 2007 he was named at hooker in New Zealand's rugby league team of the century.
Butterfield returned to the West Coast in 1958 to work in the coal mines. Rejoining Brunner Rugby League Club, he captain-coached the side to the Thacker Shield championship that year. The following year he again toured Australia with the Kiwis. In 1960 he played for New Zealand in another World Cup. He led Brunner to another championship in 1963 and also toured Australia. He'd been trying to join Australian club Manly-Warringah but the move was blocked by the NZRL. Butterfield played his final test for the Kiwis that year. He had played in 99 games, including 36 tests, for New Zealand, a record that still stands.
Butterfield remained in Queensland and in 2001 was inducted as one of the NZRL's Legends of League. He died in Brisbane on 14 February 2004 aged 72. A regional Queensland youth rugby league tournament was named after him.
