“However, they said there is an ATM outside the supermarket which is where the cash will have been withdrawn.”
A bank statement showed the withdrawal happened at 6.47pm on Sunday.
A BNZ spokesman said the bank’s cash machines had anti-skimming devices, as well as internal sensors that could detect deep skimming devices.
Deep skimming devices were inserted into a machine, rather than just on the outside.
He said the bank frequently checked its ATMs for skimming devices and, when they were detected, BNZ reviewed card use at the machine and advised other banks too.
“After dropping off over the Covid period, skimming activity has generally returned to levels experienced prior to Covid,” he added.
BNZ said skimming device technology had not changed much for several years.
“Skimmers use card readers, either attached to the outside of the machine or a deep skimmer, which is inserted into the card reader, combined with a pinhole camera to record the Pin.”
The bank said it had prevention systems to alert it to possible fraud and had a fraud detection team working around the clock.
“Where skimming occurs and a counterfeit card is used, then generally BNZ will reimburse our customers in full, normally within a few days.”
Police said offenders usually put deep skimming devices in ATMs that did not have cameras installed, or in machines in carparks where people paid for parking by inserting a bankcard.
“Deep-insert devices are generally not observable when looking at an ATM, though sometimes there can be difficulty in inserting cards or taking them back out,” police spokespeople said.
“The recording of the Pin being entered can be blocked by covering the hand entering the Pin. The stolen data is useless without knowledge of the Pin.”
Apart from covering your Pin when entering it, police said people discovering unauthorised card use should contact their bank to block the card as soon as possible.
He was caught after Customs officers intercepted a car stereo concealing two card-skimming devices from the United States.
A fortnight ago, four Romanians and one Pole were reportedly arrested in Australia for skimming.
The ABC said the group were accused of attaching a skimming device to a downtown Brisbane cash machine.
Those arrests followed a tipoff by the US Secret Service, the ABC added.
