Stan Clark began his senior rugby league career with the Parnell club. He played in their top side in 1927 and 28 which was in the Senior B grade, effectively the 2nd division. At the start of the 1929 season he was granted a transfer to the City Rovers club where he made his debut at the opening match of the season.
During the 1932 season, Clark played for Auckland against the touring Great Britain Lions. He then played for New Zealand in his only test match, which was lost 18–20 at Carlaw Park.[1]
