Between 1983 and 1986 O'Regan represented New Zealand, playing in eight Test Matches for his country.
O'Regan spent the 1981-82 and 1982-83 off seasons in England, playing for the Barrow Raiders and also represented the Mt Albert Lions. In 1987 O'Regan toured England again, this time with the Auckland side.
O'Regan later became a full time coach of the Roosters and in 1993 nearly repeated the feat, as the Roosters lost the Fox Memorial grand final 10-29 to the Northcote Tigers.
