Some of the cars came from as far as Auckland and, while many of the cars are now more than 50 years old, the weekend's events, which included trips to Waihola and the Otago Peninsula, were not marred by mishaps, mechanical or otherwise.
Convention convener Theo Marlow said one participant had suffered an injury while lying underneath his car cleaning part of it with a toothbrush, but he had won a prize for the condition of his vehicle.
Another car had taken a wrong turn on the way and ended up in Westport.
You could have "a lot of fun" travelling in a Morris Minor - "you don't have to be going too fast", Mr Marlow said.
He has a 1952 convertible and his wife Ursula has a 1961 Traveller.
The cars' machinery was very simple and most problems could be easily fixed on the side of the road, Mr Marlow said.
Morris Minors were still regarded with a great deal of affection by New Zealanders and for those interested in car restoration they were quite affordable and small enough to fit into a standard garage.
When people saw them, they always stopped to talk to their owners.
People could empathise with owners because at some stage of their life someone in their family probably owned a Morris Minor, Mr Marlow said.
He agreed there was something appealing about the shape of the car - "they're a bit cutie".
The weekend gave the 135 enthusiasts attending a chance to "talk Morris Minors" for a few days and also to show off their vehicles to the public.
While many people might be most familiar with the two-door saloon model, there were four-door sedans and other models including convertibles, vans, and the Traveller, also known as a "woody" because of its wood panelling.
The Morris Minor first appeared on the market in 1948 with some models produced until about 1973, but most of the cars on display during the weekend were from the 1960s, Mr Marlow said.
