This is probably the cheapest 2.1 soundbar that you could get that supports dolby atmos. Most of them are north of $350. You can get a JBL/Kogan one for $299 which is the same price after cashback but they are only 2 channel meaning, no subwoofer.
$399 is the cheapest ever according to pricespy/priceme. Cheapest before that was around $460ish. Reduce it further with $100 panasonic cashback promotion and you get it for $299.
There's no smiths city store in Auckland so you can have noel leeming or JB-hifi price match it for you. I successfully did one at noel's through their online chat.

if you have a Sony soundbar already that does not have Dolby Atmos is this really worth impluse buying ?
