An additional cardholder is an authorised person who can access your credit card account using a card issued in their own name.

This option applies to credit cards only. For savings, transaction, or deposit accounts, access must be set up through a joint account or third-party authority.

When it's commonly used

An additional cardholder on your credit card account may suit you if you want:

  • A trusted person to help manage shared or agreed expenses
  • Someone to access funds while you’re travelling together
  • Support for urgent or temporary spending needs

What are the benefits?

  • Can be a convenient way to manage shared or agreed spending from one account.

  • Allows someone you trust to make purchases when needed, such as for household or caregiving expenses.

  • Having more transactions in one place can make it easier to track spending and review account activity.

Things to consider

  • The primary account holder is responsible for all transactions made by the additional cardholder.

  • There’s a risk of misuse or spending beyond the credit limit, potentially risking your financial stability and credit rating.

  • Regularly reviewing statements and setting limits can help reduce risk.
