On hand to dish out the prizes on Christmas Eve was Rotorua's world champion rower Julia Edward.
Picking up Mr Uriarau's prize was Now Rotorua's Grant Kilby.
He said Mr Uriarau's idea was to provide free WiFi for the entire central city.
"We've just finished doing this for Napier's 130 WiFi hotspots and we want to be able to do the same for Rotorua," Mr Kilby said.
Rotorua mayor Steve Chadwick said the Ideas Store had worked very well and was a place for people to come and talk about anything the council was doing and offer their ideas for the future.
"It's great so many people have been involved and are passionate about the future of the city," she said.
Her grandson Manaia Chadwick had his own ideas for the city. He wanted to see more activities dotted around town for people biking through the city, like concrete table tennis tables people could play while having a break.
The Ideas Store closes on January 10.
