Henry Ford's Model T, the world's first mass-produced car, popularly known as the "Tin Lizzie", rolled off the production line from September 1908.
Its performance and affordability helped popularise motor vehicles.
When production stopped in 1927, 15 million cars had been manufactured, and 12 of them hit the road on Saturday for the Model T Ford Club of New Zealand's annual Southern event.
A group of 27 people in their Model Ts was joined by 10 people in "moderns" for the overnight trip.
The club's president, Neil Cremer, of Auckland, said there were more than 1000 Model Ts in New Zealand and he believed the enthusiasm for the historic car was strongest in Dunedin.
With a top speed of 75kmh for unmodified cars, he described driving them as an "achievement".
A group of 42 New Zealanders made the trip to the American celebrations, in Indiana, in August.
Among them was Chris Sheppard, of Ashburton, who said a Guinness world record was created, for the most Model T Fords driving down a main street.
