There are a bunch of awesome Bitcoiners in NZ, but I'm not aware of many Bitcoin-only companies. We have a lot of geothermal energy (lots of volcanoes dotted around NZ) so there's definitely heaps of opportunities for Bitcoin mining companies!
Shout out to @bitkiwi1 who puts together great Bitcoin meetups across the country and @kiwilambnz who helps out with payment implementations. There are many smart, innovative Kiwis keeping up with Bitcoin, it's only a matter of time we see more stuff coming out of NZ and entering the global stage <3
