Wellington College, a rugby based school did not promote rugby league or support union players trying out the game. Natusch was actively discouraged from entering rugby league by his then union coach John Mills, an uncapped All Black who in 2009 joined Graham Henry's All Black coaching staff in an advisory role. In 2004 Tim played his first rugby league game for the club Harbor City coached by David Fien. Dallas Penetito, Isaac Monk-Tainaghoe and Adam Cahill also played for this team. Tim attracted widespread support as a professional rugby league footballer immediately with his large upper frame, strong tackle and light feet.
