In 2001, Norris claimed another bronze medal at the 2001 FINA World Championships in Fukuoka, Japan, this time in the 200-metre individual medley, and in 2002 collected triple gold in the 200-metre and 400-metre individual medley and the 200-metre butterfly at the 2002 Commonwealth Games in Manchester. However, in 2003, he had no success in his three events, failing to medal at the 2003 FINA World Championships in Barcelona, Spain. He fared even worse at the 2004 Summer Olympics in Athens, failing to reach a single final.
