"Credit card fees are not new, ranging from petrol stations, the city council and this morning I was charged a 10 per cent accounting fee for paying for a taxi by credit card.
"With a number of high profile companies passing on these card payment fees, it should hopefully result in raised consumer awareness of the fees associated with card transactions and the relative cost of different payment methods."
Credit card companies charge retailers a transaction cost. That cost used to be absorbed by retailers but last year, a Commerce Commission into anti-competitive behaviour allowed that fee to be passed on to credit card customers to avoid non-credit card customers from subsidising costs.
On being informed of the surcharge yesterday, Consumer NZ deputy chief executive David Naulls said he expected to receive some complaints about the fee.
But he said if businesses' fees were in proportion to the costs they claimed to be covering, surcharges were "quite legal".
"This fee should be a cost recovery, not an extra form of profit."
Mr Naulls said surcharges on credit card transactions were commonplace in Australia and he expected they would be increasingly more common in New Zealand.
Consumer chief executive Sue Chetwin called Air NZ "sneaky" in August when it automatically began selecting insurance for customers at a cost of $10 per flight, leaving them to de-select it manually.
