One more lap and the race is run for one of New Zealand's most iconic motor racing venues, Pukekohe Park. In a shock announcement yesterday, Auckland Thoroughbred Racing said the venue would no longer be used for motor races as of April next year. There had been no warning of a potential announcement, leaving many in motorsport in shock. One of them was professional racing driver Greg Murphy, a five time winner of the Auckland SuperSprint at Pukekohe. He spoke to Corin Dann.
