Hi,
Are you aware of any bank that will offer a credit card that doesn't charge 2.5% when paying in foreign currency?
I've checked the big banks (ASB, ANZ, BNZ, Kiwibank, Westpac) and all of them do it.
The One Smart AirNZ card doesn't have this commission but it's a hassle that the loading of the funds take at least a business day.
Thanks.
