Kiwi bargain-hunters splashed out $62 million on Boxing Day, according to electronic transaction company Paymark.
However, retail spending - excluding food, liquor and hospitality - dropped 2.2 per cent compared to last year following a bumper spend of more than $75m on Christmas Eve.
The Saturday spend was up around 20 per cent on Saturdays in early November, before the Christmas spree started.
Spending on the day after Boxing Day was down even more at 23.6 per cent compared to last year, but the sharper decline was likely due to the day after Boxing Day being a Sunday this year.
