"It's just amazing. So many people know the movie. It's certainly been a good feel."
Mr Burr said they also saw first hand how KidsCan was helping.
The organisation, set up 10 years ago, supports the education of thousands of disadvantaged New Zealand children in 448 decile 1-4 schools nationwide.
"I didn't realise until now how much KidsCan support children in school. It's been quite a big eye opener. We visited a fully [te reo Maori] immersion school in the Far North and they were on a kayaking outdoor adventure trip which had direct support from KidsCan. They were amazed to see these guys from the big city turn up."
The Rotorua group fundraised for the organisation before the trip started with each team needing to raise $1000.
That was raised through quiz nights, barbecues and donations through their Facebook page. Mr Burr said people had also come up to them and given money when they visited each town.
He said it was "amazing" being with others who loved driving and owning Minis.
"I was 13 years old when I saw the Pork Pie movie in Taupo and my first three cars were a Mini, and my fifth car."
He had since bought several others and had spent time doing them up. "I suppose as a young teenager when the movie came out I thought these little cars were pretty exciting and have always loved them since then."
