Fijians are being urged to be cautious of unexpected phone calls from people claiming to represent ANZ and requesting personal or banking information.
The bank says reports of scammers impersonating ANZ have involved callers asking for account numbers and personal identification information, including birth certificates and source of funds details, under the guise of updating customer records.
ANZ says the reported calls are not limited to its customers.
ANZ Head of Retail Pacific Melanie Culling is urging people to pause and verify any unexpected contact claiming to be from the bank before sharing information or taking action.
She says scammers may sound convincing and create a sense of urgency to pressure people into disclosing information or acting quickly.
Culling is warning customers against sharing sensitive banking information, including their PIN, card security code, ANZ Shield code or one-time passcodes.
Customers are also being warned against transferring money to accounts described as safe accounts at someone else's request.
ANZ says it may legitimately contact customers to update their information or meet customer identification requirements.
However, anyone unsure whether a request is genuine is advised to end the call and contact ANZ independently through an official channel to verify it.
The bank is advising customers to follow three steps to protect themselves: Stop, Check and Protect.
This involves pausing before acting, independently verifying the identity of the person making contact and avoiding sharing sensitive information or transferring money when in doubt.
People are also being urged to be cautious of unexpected requests to click links, visit external websites, download software or provide personal documents.
ANZ says it has been displaying warnings about bank impersonation scams to customers in Fiji through Internet Banking and the ANZ App and will continue providing these reminders.
Anyone who believes they may have shared personal or banking information with a scammer, or transferred money as a result of a scam, is urged to contact ANZ as soon as possible through an official contact channel.
