"It's really for people who have any kind of interest in cars, especially older cars," he said.
But, Mr Nelson said it wasn't limited to car junkies.
"It's also something different for people who might not have seen these types of cars before."
Mr Nelson said it was also a chance for car owners across the country to buy, sell, and swap car parts.
Dozens of market stalls will also feature, selling all kinds of goods, food and drink.
Organisers expected about 4000 people to turn up to the event, as it had always proven popular in the past.
"Just come along and enjoy what is one of the biggest car swaps and meets in the country," Mr Nelson said.
Car enthusiast Neville Harper will be showing off his 1931 Studebaker President at the show.
He said people from across the country will head to the event.
"I know people from the South Island who are coming up for it, they just wouldn't miss it. It should be a fantastic social occasion."
The event runs from 7am to 3pm, regardless of the weather.
