Couldn't see mention of this from a Geekzone search but I've seen plenty of talk about Samsung Smart Things, which due to the hub not using the legal AU/NZ Frequency should not be used.
However it looks like in Australia they now have an AU/NZ version of Smart Things for sale using the correct frequency (unfortunately seems to ship only in Australia). Strangely the only site selling it is RACV, as linked from https://www.smartthings.com/au/where-to-buy to https://www.racv.com.au/shop/smartthings-smart-home-starter-kit.html
In the FAQ it has the question...
What frequencies do Z-Wave and ZigBee use in Australia?
The Samsung SmartThings WiFi Hub and any other devices using Z-Wave protocol and sold via RACV use the the Australian frequency and are legally compliant:
- Z-Wave: 921.4MHz, 919.8MHz
- ZigBee: 2.4GHz
Now all we need is someone from NZ to do a distribution deal with RACV to sell it here too.
