Shopping figures for December show eftpos spending is well up on last year.
Paymark, which processes more than three-quarters of all retail electronic transactions, said just over $3.2 billion was put through its network from 30 November - 20 December.
Paymark said that was almost $150 million more than in the same period last year and December has been the strongest month all year.
Chief executive Simon Tong told Morning Report he believes last Friday will turn out to be the biggest day for spending. However, transactions on Boxing Day could be down as a result.
