The series leader effectively lead the way throughout the half-hour session, his 1m13.688 coming in the first 10 minutes.
That was as fast as he went, however it proved good enough to hang on to top spot at the end.
Fellow Kiwi Andre Heimgartner went closest to knocking van Gisbergen off, his final run taking him within a tenth.
Scott Pye sat second for much of the session courtesy of a 1m13.892s before being bumped back to third by Heimgartner’s late improvement.
Will Davison edged Dick Johnson Racing teammate Anton De Pasquale in fourth and fifth while Broc Feeney was a promising sixth.
David Reynolds was seventh despite complaining of a lack of balance in his Grove Racing Mustang while Todd Hazelwood recovered from a trip down the escape road to finish eighth fastest.
Tim Slade and Mark Winterbottom rounded out the Top 10.
James Golding, meanwhile, marked his return as a full-time driver with the 23rd best time, just over a second off the pace.
That was despite having never driven the PremiAir Racing Holden before the session.
“Back where I belong, that’s what it feels like,” he said.
“I’m just getting back in a rhythm, getting used to everything in the car. The good thing is the Team 18 cars are Triple Eight[-built] as well, so all the buttons are in the same spot.
“It’s just about settling in and getting used to all of the processes again. But I’m feeling pretty comfortable.”
Practice continues with a second half-hour sessions at 2:50pm local time.
