Du Preez represented the Falcons at the 2012 Under-18 Craven Week tournament in Port Elizabeth, scoring a try in their match against the Leopards.
In 2013, Du Preez made a short move to the Johannesburg-based Golden Lions helping them reach the final of the 2013 Under-19 Provincial Championship. In 2015, he was included in the Lions squad for the 2015 Super Rugby season.
He made his Super Rugby debut, coming on as a substitute just after the hour mark and, in doing so, becoming the tallest player ever to play Super Rugby.
Tough competition for spaces in the Lions Super Rugby and Currie Cup squads saw du Preez move to the Cheetahs in January 2018 having failed to make a single appearance in either competition in 2017.
