Always the same thing with companies implementing BTC, they don't take Bitcoin directly, they use 1 or 2 3rd party.
Lols, speaking of 3rd parties...
It's thanks to a deal between Auckland startup, Centrapay(1), part-backed by Crown agency Callaghan Innovation(2), local virtual wallet company Sylo (3) and Coca-Cola Amatil (4).
It takes 4 companies to make one shitty vending machine accepting some sort of bitcoin payment...which is actually in NZ dollars.
One good thing about Sylo, seems like they are not in total control of your funds:
Important: We do not keep any record of your secret phrase. Therefore, if you forget or lose it then you will lose access to your account permanently. We strongly recommend you use cold storage for your secret phrase (that is, write it down on paper and hide it in a secret, secure location). You should not share the details of your secret phrase with anyone else. If another person learns your secret phrase, they can access your account and gain control of any funds or digital assets in your Sylo wallets.
Bad thing...
