Complaint process.

If you’re ever unhappy about something we’ve done – or perhaps not done - please give us the opportunity to put things right using one of the ways to contact us listed above.

Information we will need from you

We’re committed to resolving your complaint quickly and fairly. To help us do this, please provide us with:

  • Your name and address
  • Details of your concern
  • What you would like us to do to put things right
  • How you would like us to contact you e.g. phone number and best time to call or email address
  • Any other relevant information.

Our commitment to you

We'll acknowledge your complaint within five working days, however where possible we'll aim to resolve your complaint on the spot. If we need additional time to get back to you, we'll let you know.  We'll confirm that we're looking into your complaint, and let you know when you can expect a response.  We’ll also keep you updated on our progress.

Customer solutions.

If you have a complaint and we couldn’t resolve your concern in our branch, through the call centre or our website, you can contact our Customer Solutions team directly on 0800 351 494, or or write to us at:

Westpac Customer Solutions

Our Customer Solutions team are here to find a solution for you and will ensure that you're regularly updated about the progress we are making to resolve your complaint.

We'll always contact you to share our final response, provide an explanation of what we have found and why we made the decision.

If you're still unhappy.

If you're still not satisfied with our response after we have fully investigated your complaint, you can seek assistance from the Banking Ombudsman Scheme. The Banking Ombudsman can help customers resolve concerns and disputes with their bank, free of charge.

The Banking Ombudsman is always available to provide advice on whether the complaint resolution proposed by Westpac is fair and reasonable. We encourage you to discuss your queries with the Banking Ombudsman Scheme – providing the Banking Ombudsman Scheme with an overview of your concern and Westpac’s suggested complaint resolution. However, please note that before the Banking Ombudsman can formally investigate your complaint, it must first have been fully reviewed by Westpac’s Customer Solutions team.

The Banking Ombudsmen complaint dashboard 

Here you’ll find an industry-wide picture of what’s causing complaints and why. The information comes from banks. It helps you see how banks perform in responding to complaints and it helps banks learn how to improve their products and services. The dashboard is interactive, and you can click on different graphs for more information.
