BEDOGNI, John

Auckland businessman Jon Bedgoni and his wife Kenda keep a relatively low profile these days.

Bedgoni made his fortune as a founding shareholder in Metropolitan Glass and received a windfall of about $116 million when it was sold in 2013.

The now 70-year-old had run the company, which was founded in 1987, with three others who also feature on the NBR Rich List.

He and Kenda then set about an entirely different endeavour – building a replica Wild West-inspired theme park in the middle of the Ruapehu District's volcanic plateau.

It took four years to build, cost $8 million and didn’t see many guests but “Mellonsfolly Ranch” was a labour of love for the Western-obsessed Bedogni.

Bedogni oversaw the entire process, insisting Mellonsfolly Ranch be built with only the best materials, in the most authentic fashion possible. He and  Kenda, the former head of Chanel in New Zealand, travelled often in the Western states of the US, and once the folly began, loaded up containers with memorabilia and antiques which add to the feel of the town.

They sold up the 400ha ranch in 2012 to the Bartley family in Whanganui but the town remains a testament to their efforts.

The Bedognis have extensive property interests in Auckland and Wellington, including a $5.25m warehouse and and an eastern suburbs house in Auckland with a rating valuation of $15.5m. Their trustee company owns a number of properties in the same street. They've also set up a trustee company for their grandchildren.

Son Mat owns Hero Car Hire, an Auckland-based company that supplies unique vehicles to PR, marketing and events industries. Its main focus is movies and tv cars, including a replica Back to the Future DeLorean Time Machine vehicle. Mat, a self-confessed petrol head and who is about the same age as Michael J Fox , modified the imported car in a two-year labour of love. It featured in a Trade Me charity auction in 2015 to raise money for cancer victims.

The family support a number of charities including the Child Cancer Foundation.
