New Zealand banks are warning that some customers could have their accounts frozen if they don't respond to requests for information.
As part of their regulatory obligations, New Zealand banks are required to undertake due diligence on the foreign tax status of their customers.
To fulfil this duty, the banks recently contacted customers requesting details on their status.
"If your bank has contacted you, it's important that you respond," said New Zealand Bankers' Association deputy chief executive Antony Buick-Constable in a statement.
"Banks need to ask certain customers to provide information about their tax status. If you've been contacted, it's important that you respond to your bank, regardless of your tax status.
