Mystics coach Debbie Fuller believes a move to a more domestic-focused league would be a step back for the players.
"We love playing the Australians, we love the challenge of playing the different styles and the competitive nature of those games. Each Australian team has a different style just as every New Zealand side has a different style, and that's what keeps you on your toes," said Fuller.
Fuller also questioned whether Australia had the depth to support eight franchises.
"I don't think Australia have a case for getting more teams until they get rid of the imports from their teams. If you are going to have another team in the competition, why do you need imports? They should be able to fill those import spots first."
With the ANZ Championship entering its ninth season, the Mystics coach accepts that in order for the competition to remain relevant it is time for a rethink. But she said she would hate to see netball bosses undo all the progress that has been made to date.
"With any decision like that people have to respect the history of netball, it took a lot of work to bring our sport into the semi professional arena."
While there is concern over the future of the professional competition, the introduction of a new national league this year has boosted optimism New Zealand netball is finally addressing its depth issues. The new Beko National League will underpin the ANZ Championship, filling the competition gap between college netball and the professional end.
The Mystics principal sponsors, Sky City, have recognised the importance of the competition, signing a fresh sponsorship agreement to support Netball Northern in the new league.
