Career
After rising through the ranks of New Zealand Formula Ford, which included a third-place finish in the 2002 New Zealand Grand Prix, Gaunt moved to Australia, competing in the Formula 4000 category and winning the 2003 Australian Drivers" Championship. With Formula 4000 collapsing, the title did not lead anywhere and Gaunt returned to New Zealand. A season in Champ Carolina Atlantics followed with the Paul Newman owned Newman/Wachs Racing.
Drives in 2008 proved slim with guest drives in Toyota Racing Series, Australian Carrera Cup and a late season drive with Team Kiwi Racing in V8 Supercars.
Over the 2008/09 New Zealand motor racing summer season Gaunt competed in the Porsche GT3 Cup Challenge with the XXX Motorsport team, finishing 3rd overall and then stepped up to a full-time drive for McElrea Racing in the Australian Fujitsu Development Series. From there he was recruited by Lucas Dumbrell Motorsport to drive in the 2010 V8 Supercar Championship Series but was replaced mid season.
In 2011 he is driving for Stone Brothers Racing satellite team James Rosenberg Racing for the Phillip Island and Bathurst endurance races.
