Nothing like a late reply...
NZ didn't change the rules, Visa and Mastercard, and the Banks did
I don't believe that is the case. I believe credit card companies have always charged businesses a % fee of the transaction. Previously however I believe the CC companies prevented businesses charging extra for CC payments. This is why many businesses used to offer a discount for cash, which was essentially the same thing as cahrging more for CC payemnts. Just worded differently. But I believe changes to the laws now allow retailers to charge extra for cc payments. However there is requirement for business to charge more for CC transactions, it is purely their choice. They can instead chose to absorb them as part of their running costs.
