"In general, of course people can decide if they don't want to train with a personal trainer or prefer a cheaper option of 24-hour gyms, but specific to what we do I don't think there is direct competition."
Once fit20 opens it will cost $90 as a one-off joining fee and there are several plan options including $29 per week, per person, to train with another person or a solo rate of $39 per week to train with a trainer.
Flisijn plans to open studios throughout the North Shore and then expand into Wellington and Christchurch, and Australia, she said.
"We want to open up studios all over the country, we're aiming for 25 at first."
The franchise started in Holland nine years ago and had since proven popular in other markets, including in the UK which it launched in last year, Flisijn said.
"New Zealand people are very into sports, and I think this will attract busy people and seniors who like personal attention... so I think with an ageing population this will work well over here, the same as in other countries."
Chris Wilkinson, managing director of First Retail Group, said New Zealand has a lot of "boutique" independent gyms with small and exclusive memberships.
"New Zealand has been a pioneer in the fitness sector, with the likes of Les Mills and others, who have developed innovation and differentiation in a market where traditional gyms have become commoditised," Wilkinson said.
"Their success has inspired entrepreneurship, which we see through independent and 'artisan' type gyms and programmes so, that market is doing well, but whether there is room for a franchise model of this remains to be seen."
