Mr Taane would watch the videos and choose a winner from the entries.
"I'm not looking for something specific - just someone who is natural, enjoying it and actually wants to do it," he said.
Mr Taane would perform a set himself on Sunday afternoon at the expo before calling the winner up on stage.
"I hope it gives them heaps of enjoyment and the encouragement and inspiration to continue on making music if that's what they want to be doing."
Mr Taane said the tattoo industry was "rocking" in Tauranga despite being a rather conservative city.
The expo would be a great way to show off local and international talents - "it doesn't mean while you're there you have to get tattooed."
Mr Taane and organiser Chris Preece believed the competition would encourage families to bring their children, enjoy food and live music and look at what was new in the tattoo industry.
This year Mr Preece is amping up the expo's family vibe.
"There's more market, more food, more music. It will be a fun vibe for people to chill out on the grass and hear Tiki and other acts," Mr Preece said.
There would be more than just tattoos, including graffiti artists painting live and Benjamin Lloyd would be back airbrush tattooing kids.
"We've got the best line-up of artists we've ever had. There's heaps going on, hopefully it will open people's eyes to the fact there's a lot more to the expo."
