And every driver will be arriving with the same philosophy - "It's more fun in a Mini".
The 50-year milestone coincides with the 10th birthday of the Otago Mini Owner's Club - an organisation which is continually growing in popularity, club president Kath Morris said.
"Everybody can relate to a Mini.
"When we were children, we all knew someone who had one. Many of us learnt to drive in a Mini. These are the reasons we are all fans of the car.
We love nothing more than forming a motorcade of Minis and going on a drive together," Mrs Morris said.
The car, designed by Sir Alec Issigonis, burst on to the world's motorways in 1959, and the engineering genius's timing was perfect.
The Suez Crisis influenced the motor industry and the need to conserve oil supplies hit home.
Sales initially got off to a slow start, until celebrities were seen behind the wheel.
The Beatles had one each.
So did Spike Milligan, Steve McQueen and Marianne Faithfull.
And more recently, Noel Gallagher, Madonna, Elijah Wood and Goldie Hawn have added the Mini to their car collections.
It might be small, but the Mini has a larger than life character.
So much so that in 1999 it was voted the second most influential car of the 20th century behind the Ford Model T.
As well as being a family car, it was a successful rally car, winning the Monte Carlo Rally in 1964, 1965 and 1967.
Mrs Morris said the Otago club would celebrate the anniversaries today by meeting at the Dunedin Ice Stadium car park in Victoria Rd to display their pride and joy from 10am until 3pm.
A giant birthday cake with a Mini on top will be the centre of attention.
Tomorrow, club members will do what they love doing best - take a Mini motorcade tour around some of Dunedin's landmarks and tourist attractions, including Signal Hill, Rotary Park and Glenfalloch.
