Common questions

What is two-step verification?

Two-step verification is an extra layer of security that helps us make sure it’s really you when completing certain banking activities on your ASB account.

You may be asked to complete two-step verification when logging in, making larger payments, and certain other transactions using FastNet Classic.

Why am I getting asked to complete two-step verification when logging in?

Your ASB online account is protected by an extra layer of security. If we notice something unusual about your login, such as a new device or location, we may ask you to complete two-step verification to prove it's really you.

What is a Netcode token?

Netcode token is a small device from ASB that you can use in place of having Netcode texts sent to your mobile when doing your internet banking. It is very handy if you frequently lose service on your mobile phone, or are traveling overseas. Each token has an expiry date which can be found on the back of your token.

You can also choose to receive your Netcode via text message when using FastNet Classic internet banking. With this, you’ll receive your Netcode in a text message when a Netcode is required.

To request a Netcode token or register for Netcode via text message, call 0800 FASTNET (0800 327 863) and select option 2. If you're overseas you can call +64 9 306 3000.

We'll post your token out to you and when it arrives, just call 0800 FASTNET (0800 327 863) to activate it and you can start making Netcode authenticated transactions.

I haven’t received my Netcode. What now?

There are a few reasons why you may not be receiving your Netcode text:

  1. Your mobile coverage could be poor where you are, so please check your signal. Unfortunately, your mobile provider's signal coverage is out of our control.
  2. The phone number you're using is not set up to receive Netcode. Please check you're using the phone number (sim card) you provided to ASB for Netcode in your Personal Profile (your name at the top right-hand side of your screen) on FastNet Classic internet banking.
  3. You are overseas and may need to set up roaming on your phone with your mobile service provider. Please note, we can't guarantee Netcode delivery by text when you are overseas.

If you are still experiencing issues, you can call our contact centre on 0800 FASTNET (0800 327 863) from within New Zealand, or on +64 9 306 3000 if you are overseas, and we'll be happy to help resolve the issue.
