24-Hour Gyms? (Auckland)

Because it is a New Year's resolution and because I really have problems falling asleep right away (it is late and I am still wide-awake!), I decided to look into fitness facilities with 24-hours access. This way I have a solution to both!

All I can seem to find is Bodysmart. It seems pretty reasonable, but does anyone have any other gym recommendations? Or do you think Bodysmart is the way to go, or the only one in Auckland that is 24-hours?
