Have you used these before?

Nope... Just putting out there because I got an email from a PR person I know in the USA with a discount code.

Works out to be about NZ $76.

I've read a few reviews and the general consensus is they offer great value for money - the ANC is not terribly effective, soundstage is somewhat limited, but given the price it's a lot of headphone for the money. They'd be fine for the purposes I put headphones to, 90% of which is podcasts.

It's great to see ANC-equipped models at such affordable prices, and hopefully over time the quality of the ANC will improve. I got my wife a pair of JBLs Bluetooth/ANC for about $110 and it's the same deal there (though those are on-ear not over-ear), where the ANC is certainly better than nothing (eg, makes plane trips far more bearable) but there's not the amazing isolation that the top Sony or Bose pairs provide.
