Overall, the most money was spent on restaurants and cafes with $14.8m spent on the day.
"Paymark figures show the extent of spending at these merchants but does not show 'the why'," Paymark said.
"However, it is reasonable to presume that romance was behind this extra spending, especially as a similar pattern has occurred on previous Valentine's Days."
The company said what was surprising was a 39 per cent jump in payments to charities yesterday and a 31 per cent increase in marine equipment sales.
The 15 per cent decline in sales through building and agriculture supply companies was likely due to the weather, it said.
"In total, Paymark processed $190 million payments yesterday, which was up 4.9 per cent on the previous Wednesday.
"As a measure of the current trend in spending, annual underlying spending growth has been 4.6 per cent in the first 14 days of February, slightly lower than recent averages," Paymark said.
Movie outlets declined in spending yesterday compared with the previous week, down 15.4 per cent.
On last year's Valentine's Day, spending at movie theatres was up by 33.6 per cent.
