The New Zealand Grand Prix is the first race on the FIA's international motorsport calendar and Kiwi Nick Cassidy held off 19 international drivers to see his name etched on the illustrious trophy for a third straight time.
He took the win in the 35-lap feature race, holding off challenges from Andrew Tang and Jann Mardenborough.
The Aucklander becomes only the second driver in the NZGP's 59-year history to complete the treble, following in the footsteps of Craig Baird who managed the feat in 1991, 1992 and 1993.
Cassidy was a late addition to the Toyota Racing Series and was only contesting the last round of the championship at Manfeild over the weekend with one goal in mind - to win the NZGP title again.
It would be unfair and churlish on the other 22 drivers in the field to say Cassidy won with consummate ease.
