Which types of card transactions incur a merchant service fee?
Most types of card transactions incur a merchant service fee. However, you won’t pay a merchant service fee for New Zealand debit/EFTPOS card transactions made through your EFTPOS terminal if the cardholder selects ‘cheque’ or ‘savings’.
Pricing options.
We provide three pricing options – Blended, Interchange Plus and Interchange Plus Plus. These options give you a choice of how to pay the interchange portion of your merchant service fee and offer different benefits to your business.
Blended pricing
Simplified pricing with a fixed fee per transaction type.
Example of a Blended pricing plan:
I have a small business. A simple pricing plan that’s easy to understand provides me more certainty in what my costs are, so I can plan and include these costs in my budget.
How it works
With Blended pricing, you pay a fixed merchant service fee that includes the interchange fee – giving you cost certainty from month to month. The fee is charged as a percentage of each sale, depending on the transaction type, as shown below.

Card Present transactions are transactions where the physical card or device is presented at a terminal, including swipe, insert or contactless. Card Not Present transactions are transactions where the card is not physically presented, including online, mail order or telephone orders. Blended pricing is only available to customers that process less than NZ$500,000 in annual sales through their merchant facilities and have all facilities on Blended pricing. Charities (MCC: 8398) are not eligible for Blended pricing. |

3 New Zealand cards are domestic. If international or commercial credit card payments make up more than 15% of the total number of transactions you process in a consecutive three-month period, we may need to review your pricing option. You can find out more about when we can make rate changes in your Merchant Services Agreement.
Interchange Plus pricing
Interchange Plus offers greater transparency in fees – we directly pass on the interchange fee incurred for each transaction you process.
Example of an Interchange Plus pricing plan:
I have a growing business and value the transparency that Interchange Plus pricing provides. My customers pay using different card types, such as PayWave debit cards and business credit cards, which can incur different interchange costs. This helps me better understand my payment processing costs and how my customers prefer to pay.
How it works
With Interchange Plus, your merchant service fee for each transaction is made up of two costs – the variable interchange fee set by the card schemes, plus a fixed Westpac fee that’s calculated as a percentage of sale and covers the other acquiring costs. This means any change to the interchange fees by Visa, Mastercard or UnionPay are passed on to you.
How is the interchange fee calculated?
Your interchange fee for each transaction will vary depending on a variety of factors, including:
- Card type (credit/debit/prepaid)
- Method of payment (instore/online)
- Whether the card is locally or internationally issued.
Interchange Plus Plus pricing
Interchange Plus Plus is our most transparent pricing structure – we directly pass on the interchange fee as well as a combined scheme and switch fee for each transaction you process.
Example of an Interchange Plus Plus pricing plan:
I have an established business with transaction volumes that require a greater understanding of my payment acceptance costs. Interchange Plus Plus provides greater transparency into the different components that contribute to my payment acceptance costs, helping me better understand the costs associated with accepting card payments.
How it works
With Interchange Plus Plus, your merchant service fee for each transaction is made up of three costs – the variable interchange fee set by the cardholder’s bank, a combined scheme fee and switch fee that’s based on an estimate of the actual costs, and a fixed Westpac fee that’s calculated as a percentage of sale.
Where can I find Mastercard and Visa interchange fees?
Domestic interchange fees are updated periodically and published on the Visa and Mastercard websites. This shows the maximum interchange fees that can be applied to Mastercard and Visa transactions in New Zealand.
What are the interchange fees for Westpac issued cards?
Each bank sets their own interchange fees for the cards they provide (issue) to cardholders based on the maximum fees published by Mastercard or Visa.
The table below shows the interchange fees you’ll pay for Westpac issued Mastercard transactions. For example, if your business is on Interchange Plus pricing and accepts a contactless Mastercard consumer credit card transaction, you will pay 0.50% of the sale plus your fixed Westpac fee for that particular transaction.
