His father had bought it from a second cousin in 1933 for £50 and brought it to New Zealand in 1938.
However, he sold it not long after due to have other expenses he needed to pay for.
Mr Campbell said he spotted the car on the street 14 years later in Auckland in 1952 in a dilapidated state.
"I just happened to see it."
He knew it was his old family car instantly, there is only one other like it in the country, and managed to convince the reluctant owners to sell it back to him for £100.
Once the car was finally back where it belonged, Mr Campbell restored it and now drives it whenever he can to get coffee, to the Art Deco Festival and to vintage car rallies around the country.
New Zealand's other 1929 Delage sold recently for about $200,000 and Mr Campbell's is in better condition with a better history, he said.
Te Puke resident Daryl Nitschke watched the parade with interest alongside his mother's 1924 Douglas which he had previously entered.
"I love the variety of vehicles and seeing people dressed up in the crowd," he said.
"This is the nearest you'll ever get to stepping back in time.
"It makes me realise how much standards have slipped over the years with people going into town in their pyjamas and slippers nowadays."
The Vintage Car Parade with about 300 vehicles started at Clive Square at 12.30pm and ended at Napier Sound Shell at 2.30pm.
