We Love Colors ships to Australia - it might be worth checking if they shop to New Zealand, too, if you haven’t already.
While their customer service is fantastic and they deserve props for that, I found We Love Colors not worth the price, to be honest. I bought a few of their tights and while the stretch was ample and they fit well, they all developed holes along seams during the first wearing. Not good enough when spend that much, in my opinion. They were great and sent me new pairs - a couple of which did the same thing. So, just putting it out there as a caution, I know some people swear by them but this was my experience.
