Silly season spending is off to a slow start with consumer spending growth slower than at this time last year.
Paymark spending figures showed that although spending increased 4.9 per cent in December's first week, this was well below last year's growth rate of 8.6 per cent for the same time.
Mark Spicer, head of Paymark customer relations, said factors including lower fuel prices probably affected figures. He expected spending to shoot up in coming weeks.
Paymark also released figures for last month's nationwide spending, compared to November 2013.
Nationwide, there were 6.5 per cent more transactions last month than in November 2013. But Kiwis were spending less with each transaction, so overall spending was only up 5.2 per cent.
