He played 15 matches for the All Blacks, including two tests. He toured Australia in 1920, and in 1921 played in two tests against them. He captained the team to Australia in 1924, but a recurring knee injury meant he did not captain the 1924-25 tour of Britain and France.
He was born and died in Auckland. He went to Auckland Grammar School, and served in the Army in World War I.
His brother Vic Badeley was an All Black in 1922.
