Byron Kelleher

Byron Terrance Kelleher (born 3 December 1976 in Dunedin, New Zealand) is a New Zealand rugby union halfback for the New Zealand All Blacks, with whom he has played over 37 tests. He went to Otago Boys' High School, and originally played for Otago in the NPC and the Highlanders in the Super 14, moving north in 2004 to play for Waikato and the Chiefs. He is 1.75m tall and weighs 95kg. He was New Zealand's Super 12 Player of the Year in 1999. After meeting in 2005 Byron began a high profile relationship with pornography star Kaylani Lei, which ended in June 2006.

Kelleher had signed a contract to play for Agen in the French Top 14 after the 2007 Rugby World Cup; however, the club's relegation to the second-level Rugby Pro D2 after the 2006-07 season caused the contract to be cancelled. Kelleher went on to sign with traditional Top 14 powers Toulouse, effective with the end of the Rugby World Cup.

He is known as an unpredictable and unorthodox halfback, with his speed and strength, sometimes preferring to run with the ball and make line-breaks rather than passing the ball after rucks and mauls.
