  • Take particular care when entering into promotions such as "free trials"
  • Check the online shop has a return and refunds policy
  • Use a secure browser connection when entering credit card details
  • Check for a locked padlock or unbroken key symbol at the bottom right of your browser window or that the site URL starts with ‘https’
  • Don’t make your password easily identifiable and don’t disclose it to anyone
  • Print out a copy of the transaction record for any online purchase you make. This will be especially useful if the transaction shows on your statement under a different name that you may not recognise
  • For your safety and security, you may be asked to provide your card security code. This is the 3-digit number printed on the signature panel on the back of your Visa or MasterCard.

Westpac’s Credit Card Fraud Detection System
  • Our Fraud Detection Team operates 24/7
  • We may be alerted to transactions that look unusual compared to your normal spending history, or that match current fraud trends on credit cards 
  • Our team of experts will assess these alerts and further action will be taken where fraud is suspected

Stopping your card

  • If fraud is suspected we will try to contact you by phone, email and/or SMS first - phone calls are made between 8am and 9:30pm in your local time zone 
  • If we cannot contact you, a temporary block may be placed on the card to protect your account until we’re able to speak with you 
  • If you confirm the transactions as genuine, the block can be immediately lifted and your card can be used straight away

Unexpected declines

  • Our credit card fraud detection system may decline certain transactions that are considered to be higher risk, based on current credit card fraud trends
  • This doesn’t mean you are engaging in a suspicious transaction, but you may be trying a transaction through a retailer, country or website that is a current target for fraudulent spending
  • If your card is ever unexpectedly declined when you know you have available funds to make the transaction, please call us on 0800 888 111 or +64 9 914 8026 anytime
  • If the decline is due to a fraud alert we can fix the situation straight away

Managing fraudulent transactions

  • As soon as you advise us that a suspected fraudulent transaction has occurred on your card we will fully block and replace your card
  • If we agree that fraud has occurred, any fraudulent transactions which have been approved will be reversed as soon as possible (this may take up to a maximum of five working days)
  • In some cases we may need further details from you regarding the transactions and/or the circumstances of the fraud.  If this is the case we will contact you within three days of your claim being lodged
