Exton, the 2021 Kartsport New Zealand Sprint Champion, has quickly made a name for himself, finishing third in the 2023 Toyota 86 Championship. The Blenheim racer will be looking to repeat the success of Brock Gilchrist, who dominated the GT4 class in last year's GTNZ Championship.

While Exton is following in Gilchrist's racing boots, he won't be inheriting his car; instead, Giltrap Group has invested in McLarens all-new Artura GT4 for the programme's second iteration.
