Credit card fraud can happen to anyone, as recent victim - and Police Minister - Stuart Nash can attest.
Mr Nash's wife's credit card was ripped off by more than $1000 - ironically, a day before he launched Mastercard's new cyber safety guide, in Cyber Smart Week.
"My wife phoned up and said 'I tried to buy some fish and it bounced'," Nash told NZME.

The fraud involved multiple transactions to Apple. The couple are trying to retrieve the money.
Mr Nash didn't regularly change his passwords and admits he was "a little bit blasé" in regards to cyber security.
"Certainly now we're going to go and change all passwords, but do it on a regular basis as well."
Experts recommend changing passwords regularly, as well as updating security software and backing up data.
