Poorer households in New Zealand are subsidising higher-income households to the tune of $59 million a year through credit card reward schemes, an issues paper from the Ministry of Business, Innovation and Employment says.
The paper estimates that the total cost of merchants increasing their prices to fund rewards for credit card users is $187 million a year. The total additional cost to the economy of the current system is put at $45 million a year.
Credit cards make up 42 per cent of transactions by value, 36 per cent of transactions are through eftpos, 15 per cent by traditional debit card and 7 per cent by contactless debit card.
The report notes that New Zealand has the lowest proportion of cash in circulation compared to the size of its economy of anywhere in the world.
The report notes that merchants in New Zealand appear to pay higher fees to accept payment via credit card than merchants in some overseas countries, with fees roughly comparable to the USA and Canada. Fees are significantly higher than in the European Union and Australia, where they are regulated.
