The massive crowds and positive support for the venue from drivers and administrators may well have clinched the deal for ASB Baypark to host a round of the 2016 World Jetsprint Championships to be held in New Zealand.
Jetsprints Bay of Plenty event director Pip Minnell says the world series had a potential international television audience of 38 million.
