"Challenge and Dipper were worth the drive from the smoke to the steam. The old roads were still there, but trails with berms and jumps, well, that was truly mind-expanding," Gaz continues.
"When we decided to launch an apparel business aiming at mountain bikers, a move here made a lot of sense. When mountain biking became the popular activity we knew it would, we believed Rotorua would be at the heart of the sport in New Zealand."
By the time Nzo opened its doors the network had extended to include what is now Tahi and Creek.
"We were several years into the business before Rock Drop and Rosebank opened. I was amazed by a day I spent riding every purpose built trail in the forest in a complex loop, and totting up 32km on my primitive cycle computer [which lasted about three rides before the wire got torn off]. Hard to believe, the entire ride was on the Waipa side of Nursery Rd.
"Trees have been mowed down and trails have been reformed, trees have grown back and the rebuilt trails have matured. It's like that old bike that's had two warranty frames and three new drivetrains - the same, but different."
Nowadays, the visitors to the trails, on an average weekend, number in the thousands.
"The trail system's expanded to the far reaches of the forest - and also to the far corners of the earth. Several trail building companies based here export the 'Rotorua style' to the world. Because of events, like the 2006 World Championships, the Singlespeed World Champs, and the incredible success of Crankworx, every year, Rotorua is one of the best-known riding spots on the planet.
"Numerous cities all over Australasia are throwing a lot of effort and funds at trying to emulate what a cast of hundreds, over several decades, has achieved here. That's great, and some will become great places to visit.
"After 20 years of living and riding and working in Rotorua, Glen and I wouldn't live anywhere else."
