Westpac Online Guardian.
Online Guardian is our secure fraud detection system developed to help make your online banking experience safer.
Set up your challenge security questions & register your mobile.
If you’ve been using online banking for a while, you should have your challenge questions already set up on Westpac One®. Recently signed up? You will be able to set-up your questions when you first register.
You can also choose to register your mobile number in Westpac One to receive verification codes by text message. For payments within New Zealand a new phone number will be automatically approved by Online Guardian after 30 days from registration (unless verified in branch or via our call centre). International payments require a further 7 day wait period once your new phone number has been approved by Online Guardian.
We recommend registering your mobile number so that you can continue to bank safely.
