Where is the security code on my Westpac Debit Mastercard?

You'll find the 3 digit security code on the back of the card. 

If the code is no longer visible on your card

Over time these printed codes may fade, or damage to the card may make it hard to read. If you can't read your code, call us on 0800 400 600, Monday to Friday 7am to 8pm and Saturday and Sunday 8am to 5pm. Or on +64 9 912 8000 if you're outside New Zealand (standard call charges will apply) and we can let you know what it is. If you'd like a replacement card, there is a charge of $10 and the card will take five to ten days to arrive. (If you use your card for any automatic bill payments, you will need to advise them of the new expiry date of your new card as well.)
