My wife had an email from ASB today warning about suspicious activity on her credit card. An initial charge of $4 was made by Apple NZ GCS Sydney AU. Then two days later, a further $19. My wife does not even have an Apple account, and has no idea where they got her details from.
Google finds a lot of hits referring to the same identity, including a Geekzone thread from May last year. That thread is locked though.

So keep an eye open. ASB advised my wife to cancel the card concerned, and are investigating the charges. They are definitely waiving the $10 new card fee, but the other $23 is in the hands of the ASB investigation department. The Google hits mention hundreds of dollars, and it sounds like they ramp up activity if you don't get on to it. But what the heck do we do to safeguard against this sort of thing. Are we at the mercy of scammers every time we purchase something online using a credit card?
