Bank card users are being warned again to keep their PIN numbers secure and be aware of any unsolicited approach from people offering prizes.
Banking Ombudsman Deborah Battell said her office was dealing with frauds and scams involved pilfered PINs on a daily basis.
Ms Battell, formerly of Wanganui, said the scammers were not just targeting the elderly and vulnerable and were using "all sorts of tricks" to get people to reveal their bank card PINs.
Ms Battell told the Chronicle that while scammers targeted certain sections of the community, others fraudsters did not.
"For example, they'll use small cameras to record keystrokes someone may use at an ATM so that sort of thing doesn't target just one section of the community. It's anybody."
