Bank transfers are one of the most commonly used payment methods at online casinos, including those accessible to New Zealand players.
When withdrawing funds, some international casinos may request banking details such as IBAN or SWIFT codes to process payments.
Understanding these terms helps explain how international casino payments are handled.

What Is IBAN?
IBAN stands for International Bank Account Number.
It is mainly used in Europe and certain other regions to identify bank accounts for international transfers.
An IBAN helps ensure that money is sent to the correct account when crossing borders.
What Is SWIFT / BIC?
SWIFT (also known as BIC – Bank Identifier Code) is a global banking system used to identify financial institutions during international transfers.
It helps route money between banks in different countries.
Do New Zealand Banks Use IBAN?

New Zealand does not use IBAN for domestic banking.
Instead:
- Local transfers use standard bank account numbers
- International transfers use SWIFT/BIC codes

How Casino Withdrawals Work for NZ Players
When withdrawing from an offshore casino, you will typically need:
- Your bank account number
- Your account holder name
- Your bank’s SWIFT/BIC code
- Sometimes your branch details
Funds are then transferred internationally via the SWIFT network.
When Do Casinos Ask for IBAN or SWIFT?
Casinos may request these details when:
- Processing international bank transfers
- Sending funds from outside New Zealand
- Using European-based banking systems
However, NZ bank transfers usually rely on SWIFT rather than IBAN.
