Netball NZ's plans for expansion has also created churn, albeit on a lesser scale.
The addition of a second team under the umbrella of Netball Northern creates massive challenges for zone management, who are still struggling to make one franchise profitable.
Netball NZ chief executive Hilary Poole said the national body are prepared to financially support the new franchise through the start-up stage.
"It's at the point where we have realised Netball NZ needs to own and underwrite a team to get it up," she said. "The time frames are really scary, it's pretty tight."
Poole said a working party with representatives from Netball NZ and Netball Northern management has been established to work through details such as location, a team name, and coaching and management personnel.
"We will be resourcing it with a franchise general manager, who will work with the working party and the board and because it needs to operate with fairness, it's important it will be governed with independence."
Netball Northern chairwoman Dianne McAteer said while she is confident Auckland netball has the fanbase to support a second team, her biggest concern is finding commercial partners in a congested Auckland sports market.
The new team will not only be competing with the Mystics, but also the Blues, Warriors and Breakers for the sports sponsorship dollar.
"The sponsorship, commercial partnership pieces are a real challenge for us. There is an opportunity to spread the overheads of two teams in a more cost-effective way than we are currently, so we will look for a potential upside there," said McAteer.
