Senior Constable Tracee Knowler, of Houhora police, said she suspected many people had been targeted around the North. Luckily the people who had contacted her realised it was a scam.
"I can assure you all that no legitimate outfit would ever ask you for those details (bank account and PIN numbers). They are simply scumbags hoping to use this opportunity to fleece what they can from our community and our people that are already struggling," she said.
She urged anyone called by the scammers to take a note of the phone number, if it appeared, and pass it to the nearest police station. The number for Houhora police is (09) 409 8822.
Ms Knowler said the scammer sounded convincing and "reasonably professional".
