A limited-edition Bentley GT3-R Supercar worth an eye-watering $540,000 has also been part of a huge car and motorcyle display.
But the place to be at lunchtime today was the unveiling of the hoverboard.
A copper-topped skate ramp has been specifically installed at the event. The metal surface combines with a magnetic system mounted beneath the board to create a magnetic field which lifts the board from the ground.
The technological wonder was imported by local entrepreneur Jamie Vujcich who unveiled the gadget.
The hoverboard concept was famously part of the cult Back to the Future movie trilogy but science fiction has now become science fact.
The bad news is the the batteries on the cutting-edge machines - which can levitate - only last around seven minutes.
Vujcich says he wants to see special parks created as the technology continues to develop.
"This is just the beginning, we envisage hover parks and all kinds of new applications in the future" he said.
Big Boys Toys continues today and tomorrow at the ASB Showgrounds in Greenlane.
