"We actually lost count of how many people turned up to show off their vehicles this year, there were so many," he said. "This is an event which is supported very well by locals and it's also an excuse for people from out of the town to come for a drive and show off their pride and joy - their vehicles."
Mr Mills said Wheels with Attitude benefited the cancer support group and there appeared to be economic benefits for the town as well.
"Visitors spend in town, in particular at service stations, cafes and second-hand shops, so I'd like to see the whole town get behind the event," he said.
As visitors flock in from around the North Island, Mr Mills said it's time to extract as much publicity and financial return as possible. However, with the show on the fast track to becoming too big for members of the wheels club to handle, he said help with controlling crowds and staging the event will need to come from somewhere.
"We'd like to have some help on the gates at the very least," he said. "We donate the proceeds to the cancer support group because we realise it is a very worthwhile cause, but also they help us out with sun lotion and umbrellas on the day."
