In the Waikato, transaction volumes rose 7.2 per cent to 3.48 million, with a total December spend of $165.3 million, up 3.6 per cent compared to last year's $159.5 million.
Wellingtonians have spent $221.4 million so far this month, up only 1.4 per cent on the previous December, with 4.97 million transactions -- up 2.9 per cent.
In Canterbury, spending was up 3.2 per cent to $268.8 million compared with the same period last year, with 5.31 million, transactions.
Taranaki, West Coast, Southland and South Canterbury all showed a decrease in spending compared with December 2013.
Paymark's head of sales and marketing Paul Whiston said that overall, December spending within the entertainment and hospitality sector, which included accommodation, cafes and bars, was up 9 per cent compared with this time last year.
Spending at supermarkets was up 7.9 per cent from 2013 and spending on books and video was up 6 per cent.
Mr Whiston said the figures were steady, with two big spending weekends yet to come.
"We know from MetService figures that it's been the coldest start to summer since 2006, which may influence shopping behaviour.
"Additionally, an increasing number of retailers are starting their Boxing Day sales before Christmas. This may result in an increase in the number transactions we're processing but the value may be slightly lower." Paymark processes more than 75 per cent of all electronic transactions in the New Zealand retail market.
