Northlanders splashed out more in December than in the same month in 2014, according to Paymark figures.
Paymark records show $2.235 billion was spent across the Paymark network in Northland and Auckland in December - 9.2 per cent more than in December 2014.
Assistant manager Kelly Shepherd, from Whangarei children's book and toy store Storytime, said the shop seemed busier in the lead up to Christmas than in 2014.
"There were a lot more people around. We were busy right up until the last minute. People normally have most of their shopping done by Christmas Eve, from a gift point of view anyway. It's normally the food shopping that gets done at the last minute. But Christmas Eve was one of the busiest days."
Ms Shepherd expected Christmas Eve was busier-than-normal because it fell on a Thursday.
