Director Dean Cornish said among the Rotorua people they filmed were Noel Hyde and Debbie Stewart, of Wingspan National Bird of Prey Centre, Katie Williams of the Kiwi Coffin Club, Rosemary and Ray McCully, and Tak and his brother Tuhua Mutu, of Multi-Day Adventures.
The crew of four spent yesterday afternoon filming the brothers as they took Trenz delegates on a mountain-bike tour at Waipa Mountain Bike Park.
"Each episode is in a different provincial area, Rotorua is a bit bigger for us but it's still interesting. All about the people, good buggers doing interesting stuff. Researcher rings around, puts her sniffers out," Mr Cornish said.
"It's been great to meet interesting people who contribute to the community, they have their own stories to tell, great people doing amazing stuff."
