The National Basketball League of Australia and New Zealand is down to just six teams.

Townsville and Wollongong have each entered into voluntary administration.

Andrew Gaze, speaking on his SEN Radio show ‘Morning Glory’ on Wednesday morning, said the NBL should close its league and only relaunch it when it's ready.

“I have never held this view at all throughout this challenging phase of the NBL, but I have reached a position where I think they are better off regrouping and shutting it down,” Gaze said.

“Even if these two teams (Wollongong and Townsville) somehow find a way to get through administration, nothing is going to change significantly to turn around their plight because it is a slow burn.

“So shut it down, regroup and get the right model because the model is broken.”
