This weekend marked the second year the event has been held at Peter Johnstone Park, and co-organiser Regan Horrell was pleased with how the day had gone.
Hundreds of people were checking the event out late yesterday morning, despite the wet weather.
Among the attractions was a "kids' alley" series of activities, including a bouncy castle and motorbike riding, a line-up of musicians and entertainers, including locals such as 16-year-old Liam Boyne, and rock band Th'Leftovers, whose frontman was Mosgiel man James Mckewen.
The day also featured the Otago Museum's "Lab in a Box", which drew plenty of parents and children in, and helicopter joyrides, provided by Highland Helicopters.
"The whole event is very community-focused, bringing the community together. It's a good family day out," Mr Horrell said.
Holding the event in the park had been a good move, he said.
"It has huge potential to grow, year after year."
"Lab in a Box", run in conjunction with the University of Otago's Department of Physiology, included a virtual reality headset, allowing children to explore three different sites in the Antarctic, as well as a whole host of activities designed to educate children about the human body and teach them how to to look after themselves.
Otago Museum science outreach project co-ordinator Clarie Conconnan said the lab had recently been to schools in the Catlins, Invercargill and Balclutha.
"They love it [the VR component of the lab]; it just feels like you're there," she said.
Another hit for young children was a monster truck, and cars at the show included Maserati's Levante SUV, which was being promoted by Married at First Sight NZ contestant Dave McClelland.
