One of New Zealand's unsung motorbike legends, Bruce Anstey, has again hit new heights at the annual Isle of Man TT road racing championship.

Organisers of the V8 Supercars ITM 500 racing at Pukekohe say they are overwhelmed by the reception from locals and the thousands of visitors from around the country and Australia.

The grand old lady of New Zealand motor racing circuits, Pukekohe Raceway, put on one hell of a display in welcoming back the V8 Supercars circus last year after a five-year hiatus.
