Scammers are attempting to collect personal and banking information. They are constantly changing the message so it appears to come from different banks and link to different URLs.
The Ministry of Business, Innovation and Employment's Consumer Protection team said it was difficult to distinguish the scammers' fake bank websites from the real ones.
Here are some ways to keep yourself safe from this scam and others similar to it:
Never enter your personal details into a website unless you are sure it is genuine.
Check website addresses carefully. If they’re similar to a genuine company’s URL, but not quite right, be wary.
Never visit your bank's website by clicking on a link - type in the website address yourself.
Don't give out account details over the phone unless you made the call and you trust that the number you called is genuine. Ask for a name and number so you can call them back, and check that number against a number you know to be genuine.
Check your account statements and credit card bill to make sure no-one is accessing your accounts. Order a credit report every year to make sure no-one is using your name to borrow money or run up debts.
