He spent 1994 with the Western Suburbs Magpies, playing in only seven matches after having knee and ankle surgery during the off season. In 1995 he was part of the inaugural squad for the new Auckland Warriors franchise and played in the centres for the Warriors in their first ever competition game, a 25-22 loss to the Brisbane Broncos in front of 29,220 fans at the Ericsson Stadium in Auckland.
