Roose debuted for Otago in 1988 as a hooker. After four seasons he switched to play for Counties in 1992 and scored his first NPC try that year. He was noted as being a more mobile player than would normally be expected of a hooker.[1]
In 1996 he was signed to play for the Blues in the inaugural Super 12 season.[2] He spent 16 games on the bench without playing a match until March 1997 when he played the final 5 minutes in a match against the Queensland Reds.[3] After Blues captain Sean Fitzpatrick was injured he saw more regular appearances afterwards.[4]
In April 1999 he made his debut for the Chiefs, replacing the injured John Akurangi, who was out with an infected ear.[5]
In June 1999 suffered a neck injury in club training, knocking his head on a scrum machine pad and then lost feeling in an arm. His career was in doubt and ruled out for the season.[6] He was not named in the Counties squad for the 1999 NPC and retired.[7]
