How do I dispute a Standard transaction?

If you identify an unauthorised transaction on your account, call us straight away on 0800 500 450 from NZ or +64 9 580 7365 from overseas. For peace of mind, you can also temporarily place your card on hold by logging into My Account so the card can’t be used.

If you wish to dispute a Standard Purchase or cash advance transaction (e.g. charged an incorrect amount, services not provided, goods not received, ATM has disbursed the incorrect amount of cash) you will need to complete a Notice of Disputed Transaction form.

Please return the completed Notice of Disputed Transaction form and any applicable supporting documentation to [email protected], or alternatively via post to: Hummgroup Chargebacks and Disputes, PO Box 94013, Auckland 2241, as soon as you identify the disputed transaction.

Once your documentation has been received, it may take up to 30 days for us to respond and confirm whether additional information is required.

For any travel related disputes please contact the relevant merchant to seek assistance. The merchant will take action and deliver the appropriate outcome as stated in their terms and conditions.
