Pak'nSave has issued an "unreserved" apology for mispricing products at its Kaitaia supermarket, after a customer revealed that staff began advertising specials before the lower prices took effect.
Doug Cochrane, a spokesman for Pak'nSave owner Foodstuffs, confirmed staff in Kaitaia had been changing price labels while the supermarket was still open on Sunday, before specials took effect the next day. This meant some prices were incorrect, and customers were overcharged.
"Changing tickets prior to the start of a promotional cycle is not acceptable and is not consistent with pricing integrity policies," Mr Cochrane said.
"I would like to apologise unreservedly to our customers in Kaitaia, who, while they were charged the correct price, may have been misled by incorrect shelf pricing."
Customers who believed they had been overcharged could be entitled to a refund, if they had their receipt.
