While ANZ Championship general manager Andy Crook admits the poor performances of the New Zealand sides have undermined the new model, he said the organisation is not considering a change after one season.
"We always review things, but at the moment there is no discussion about going back," said Crook.
"There is a lot of work to do in New Zealand, but that's nothing to do with the conference model.
"The strategies and high performance environment needs to be right if teams are going to be competitive, and that's up to Netball NZ to address."
Crook argued that in many ways the conference system has been a success. Australia has seen a marked increase in crowd numbers this season, already breaking attendance records with potentially two games remaining across the Tasman.
"From the very start, one of the key objectives of this model was making sure our franchises survived and started thriving in a really clustered market-place. We simply cannot have our teams out of finals contention after five games - it doesn't make sense commercially."
