Privacy and security

Protecting your privacy and security

Our banking systems provide extra security to keep your personal and financial information and account details safe when you are banking online or on a mobile; or using cheques and our range of cards. Some of our security features use two-step identity identification and others use special techniques developed by us or our providers. We can even identify you, when you call us, using your voice with voice biometrics, which is even more secure than using your fingerprint as a form of ID - and you don't need to remember a PIN. It is also important that you take steps yourself to keep yourself secure online.

Our banking systems provide extra security to keep your information and accounts safe. Some use second factor identification, others use special techniques developed by us or our providers. Once enrolled, we can identify you using your voice with voice biometrics, which is even more secure than using your fingerprint as a form of ID - and you don't need to remember a PIN.

Other systems use special techniques developed by BNZ or our providers. There are also a few simple steps you can take when using cheque, card or internet and mobile banking services.

We alert you about security issues

We publish security alert messages on the login pages of our Internet banking services if there is any suspicious activity, to let you know what's happening. We'll also tell you if there is anything extra you can do to protect your identify and money from the risk of online fraud.

When you use our Internet Banking services, you are protected by NetGuard or Mobile NetGuard if you are using the Mobile Banking app, adding an additional layer of security to our other systems and procedures.

Protect yourself online

There are steps you can take to help keep your computer and your personal and financial information safe when you are banking or doing anything online.

Get anti-virus software

You can protect your computer's hardware and software from internet threats like malware, which includes computer viruses, spyware, trojins, and rootkits, by installing and maintaining reliable and reputable anti-virus (AV) software. These Internet threats often infect computers through compromised websites, email attachments, and affected files from attached devices such as a USB sticks and then corrupt and delete data on your computer and/or use your email account to infect other computers by sending illegal spam emails. If your computer is running really slowly, it might be sign it is infected. To help keep your computer virus-free, make sure:

  • your AV software is configured properly so it doesn't slow your computer down
  • your AV software is configured to automatically update everyday
  • you schedule a weekly AV scan of your computer. 

Did you know?

If you are a BNZ Internet Banking customer, you won't have to worry about Internet threats while you are using Internet Banking online, because NetGuard helps to protect your account(s) against malware.

Have a strong password

You should make sure you have strong passwords for all your different Internet accounts, not just your Internet Banking account. This increases your security online and reduces the risk of someone accessing your accounts and taking your personal information.

Check the sites you visit

If you are using publically accessible computers in Internet kiosks or accessing the Internet via free public Wi-Fi, you should check the security certificates on any websites you visit. Also, check the address bar – if it shows “https://” (instead of “http://) that means the  connection is more secure.
