Grocery prices will continue to hit Kiwi consumers and our economy hard. 

A report by the Commerce Commission shows prices are increasing again this year after appearing to stabilise last year.

She says that unless the two major supermarkets know that they’re going to face proper regulation or something big will happen to them, they can continue to charge high prices.
