A stand-off, Lang represented Auckland provincially. Lang played for Maritime in the Auckland Rugby League competition from 1919 to 1921. During the 1921 season he applied for reinstatement into Rugby Union but was refused and when he returned to league he switched to the Marist Old Boys club.
He was a member of the 1919 New Zealand Kiwis team that played Australia. Lang played in the first test, but did not represent New Zealand again afterwards.
