Fitbit Charge HR (Black/Large)
Fitbit Charge HR (Plum/Large)
Fitbit Charge HR (Teal/Large)
Earlier today there were small ones available for the same price. They seem to have disappeared off the website though. I would say they are still available in store.
Dick Smith have had them for $138. There was/is barely any stock though.
I think Dick Smith have them cheaper ($138), but only two colors: http://www.dicksmith.co.nz/fitbit-charge-hr
