Mr Thompson said the skimming device was a "hit-and-run kind", which the fraudsters attached for short periods.
In this particular case, the scammers waited two months before they acted on the information gained from the Paraparaumu scam, and withdrawals were made from four different countries.
"What they do is, [the device], it reads the cards and normally there is one small camera," he said.
The information was stored and sent overseas and duplicate cards were created. These were then used to try to remove funds from accounts.
Mr Thompson said skimming-device scammers were quite common and were sometimes active in New Zealand.
"We can't stop it but we can make sure we reimburse the customers," he said.
"We just have to wear that. It's part of being a bank."
Mr Thompson conceded the scammers would get away with money.
Tips to prevent being scammed at ATMs:
1. Cover your PIN number with your hand. This ensures any hidden cameras don't pick up the number, so ATM skimmers can't access your account.
2. Use familiar ATMs and limit your visits.
3. Check your bank balance frequently. Report anything unusual to the bank immediately.
4. Look at the ATM before you use it. If something doesn't look right, alert the bank and use another machine.
