The five children came from different areas of the Upper Clutha area and were dressed to represent facets of the show and the community - farming, fashion, rugby, sustainability and horse riding.
Bailey was particularly excited to be riding her pony Gundagai Murrawagga in the first ridden section, making her show riding debut, while Nova enjoyed looking at her art entries.
All five would be making an appearance in the show's traditional grand parade on Saturday, being driven around in a car.
As well as the billboards, there were also videos released that featured locals discussing what it meant to be a Wanaka local.
The Wanaka A & P Show, which is on this Friday and Saturday, is one of the country's largest agricultural and pastoral events, attracting more than 40,000 people.
It was estimated to bring more than $10.9 million worth of direct economic benefit to the local community each year.
