Wairarapa shoppers spent more than $46 million in December, up 5 per cent on the same period last year, new Paymark figures show.
The December surge capped the fastest year of spending growth since the recession, with $49.3 billion in transactions made nationally during 2013, up 0.2 per cent on the previous year.
Pet stores recorded some of the month's highest growth.
Owner of Masterton dog groomers Pampered Paws Dionne Pugh said the number of pooches coming in for a grooming doubled ahead of Christmas.
"They [owners] like their pets to be all spruced up, nice and clean and pretty for Christmas."
