Organiser Phil Scorringe, of Bikers Rights Organisation New Zealand, said in more than 30 years of managing the event, he had not seen weather like it.
"[We have] never had hail here before — but it was short, sharp and sweet."
Last weekend’s event was the 39th year of the rally, and 650 people were in attendance.
Mr Scorringe said while numbers had been slightly down due to other events around the region, the rally had a carnival-like mood.
"It’s always a good atmosphere here."
The rally was organised and run by volunteers, who loved to see people enjoy the event.
"The reward is just seeing the looks on people faces."
"[We get a] variety of bikes and variety of walks of life — we have everything from gardeners to policemen."
People saw the rally as a way of catching up with people they might not have seen since the previous year’s rally — some coming from as far as Whangārei.
Proceeds from the Vincent County Rally will support the Muscular Dystrophy Association, the Otago Southland Rescue Helicopter and Heart Kids New Zealand.
"We run this event purely to help our charities," Mr Scorringe said.
He thanked the event’s sponsors, whose support meant money could be donated and not caught up in operational costs.
Attendees Arran and Tracy Mason, of Dunedin, said they had been coming to the rally since 2006.
Mrs Mason said they had met many close friends through rallies.
The couple had come to the Vincent County Rally for the "friends, companionship and motorbikes", Mr Mason said.
