The Kiwi contingent started the day in the ideal spot with the Shell V-Power Fords of Scott McLaughlin and Fabian Coulthard sharing the front row and defending series champion Shane van Gisbergen starting third in his Red Bull Holden.
Coulthard was the first to run into problems when his tyre exploded just short of his first pit-stop. It appeared the misfortune would cost him any chance of over-taking van Gisbergen for the series lead.
McLaughlin and van Gisbergen avoided tyre trouble and appeared ready to battle out a win but both drivers and Ford's Mark Winterbottom were served 15 second time penalties for incorrect pit entry, throwing the race wide open. A somewhat vague warning had been issued earlier in the day but all of the leading teams were caught out with the application.
In total seven cars were hit with penalties as further video evidence came to light.
A couple of safety car interventions in the second half of the race at least eased the workload on the tyres and further issues were avoided but it did mess with the strategy of many teams.
When it all played out Coulthard managed to over-take Garry Rogers Motorsport's Garth Tander and take the win. The Red Bull Holden of Jamie Whincup was second and Tander held on for third.
Van Gisbergen ended up fourth and now finds himself 10 points behind Coulthard in the overall standings.
"Not the way we wanted to win a race under the safety car," Coulthard said.
"We went through our fair share of misfortunes but we had a good car and a fast car."
Whincup admitted he didn't have the pace to match it with the top cars but was happy to avoid drama and secure a podium finish.
He thought the tyre issue was more about drivers and teams pushing the boundaries rather than a malfunctioning Dunlop tyre.
"It isn't a Dunlop issue - everyone is pushing the limits and when you push the limits you sometimes step over them."
A second 250km race will take place Sunday with all eyes on how teams manage to deal with the tyre issue.
