Helping you to keep your card safe.
We're always on the lookout for new ways to improve our leading-edge fraud detection systems. LENSecure is a revolutionary technology invented right here at BNZ. On this page you'll find out how LENSecure works, and other great tips to help keep your BNZ credit card and Flexi Debit Visa safe.
World leading credit card security
LENSecure is a breakthrough in credit card security and combined with our other security measures, makes BNZ one of the world leaders in credit card security. LENSecure helps us detect if your BNZ credit card (VISA, MasterCard or American Express) or Flexi Debit Visa has been copied or duplicated without your knowledge. Most importantly, this can automatically prevent counterfeit credit card transactions, reducing the likelihood of your Card being cancelled and having to wait for a replacement card to arrive.
How LENSecure works
Each time you use your BNZ credit card or Flexi Debit in one of our ATMs for a balance enquiry, mini statement or cash advance1/cash withdrawal, LENSecure automatically updates the security information on your card's magnetic stripe. So, if someone does manage to make a counterfeit copy of your card, it'll be out of date pretty quickly.
So, to help protect yourself:
- Regularly use any BNZ ATM to complete a balance enquiry, mini statement or cash advance1/cash withdrawal.
- Prior to going overseas, and again as soon as you can upon returning to New Zealand, we recommend you complete a balance enquiry, mini statement or cash advance1/cash withdrawal at a BNZ ATM.
- If your account has a joint or additional cardholder then please ensure the joint/additional cardholder follows the same process for their card.
Zero Fraud Liability Guarantee
We're working hard to keep your card secure so you can feel safer using it. We also guarantee you won't lose out if you're the victim of credit card fraud, as we'll repay any fraudulent transactions as long as you have complied with your credit card terms and conditions. These include notifying us promptly of any fraud, selecting a suitable PIN and protecting your PIN.

Our Visa and MasterCard credit cards are issued with chip technology that helps prevent fraudsters from using a counterfeit credit card in stores or at ATMs. The chip on the credit card along with the PIN authentication creates an even more secure transaction when you're physically using your card.
Contactless chip cards
Our Flexi Debit Visa card and our Visa and MasterCard credit cards are issued with contactless chip technology. This means you can use your card to quickly pay for purchases of up to $80 in New Zealand without needing to enter the PIN.
Added security measures for contactless transactions include:
- the card never leaves your hand.
- because the card has to be very close to the reader there is no chance of being accidentally charged as you walk past.
- you can only be charged once, even if you accidentally tap your card twice.
What is BNZ doing to minimise the risk of fraud on cards with contactless chips?
An $80 limit applies to each contactless purchase without a PIN made with your contactless card in New Zealand. For purchases above $80, your PIN will be required.
Our chip cards are issued in a deactivated state, which means you can’t use your new or re-issued card until you have activated it. To activate a new card, just visit any BNZ store to get a PIN loaded on the card. For re-issued cards it's even easier, because the PIN from the previous card has been migrated to the new card. All you have to do to activate the re-issued card is use it for a contact transaction that requires you to enter the PIN.
Our cards also have Zero Fraud Liability guarantee which means you won't have to pay for fraudulent card charges as long as you have complied with the terms and conditions of your card.
If I have any other contactless cards in my wallet, such as a Hop, Snapper, One Smart card or another credit card, could the purchase be charged to the wrong card?
If you hold your wallet up to the reader, it may detect more than one card. In this case it will not complete the transaction, and will display a message such as "More than one card detected" or "Please select one card". To complete the transaction, you'll need to ensure only one contactless card is held to the reader. Learn more about contactless payments.
Are there any special security measures in place when I use the card overseas?
Overseas, some standalone or unattended terminals, such as vending machines and parking terminals, do not "talk" to the bank's systems during the transaction. After a certain number of these transactions have happened in a row, your next transaction may be declined. This is easily fixed by using a chip insert terminal for your next transaction – this includes most attended terminals. This will require you to enter your PIN or sign, and confirms the card is in your possession.
Keeping an eye on your account
It's a good idea to check for unusual transactions on your credit card account. This can be done by checking the monthly statement, or logging into internet banking. Please contact us immediately if you notice any irregular transactions on your account.
