The Commerce Commission says shoppers are likely to be losing millions of dollars a year due to supermarket pricing errors.

Grocery commissioner Pierre van Heerden has called them out for times when the price on the label doesn't match what you end up paying at the counter. 

He believes when that happens they need to give you the product for free.

Head of research and advocacy at Consumer NZ, Gemma Rasmussen, told Heather du Plessis-Allan it should be the role of the commission to be looking into the pricing discrepancies.

She says 65% of shoppers are noticing pricing inaccuracies when they go to the supermarket and about 12% are spotting them frequently.
