It can be challenging to train and keep good staff in shearing says Mullins, especially when there are more opportunities for remuneration overseas.
"It is a global sector now and when our staff can double their income just by going to Australia ... and triple it by going into the Northern Hemisphere, it becomes a lot more challenging to keep out people and keep them home, especially when we need it. So there is still a lot of work to be done in that area."
Mavis and her husband Koro stay close to the Golden Shears competition as it's a "fabulous event" that gives people "the rock star opportunities." Although Mullins says she gets to see "the new guys coming through," at The Golden Shears, the challenge is to keep them in the industry.
Shear Bro is going to be a realistic portrayal of "the challenge of the business of shearing ... I would say it's warts and all," says Mullins who confesses that she forgot the camera crew were there sometimes.
"These people are around you 24/7, they almost become a little bit invisible to you, so it'll be interesting. It'll be fun."
Watch Shear Bro on Māori Television at 8:30pm July 10th.
