The Government's issued a fresh warning to the major supermarket chains. 

Economic Growth Minister Nicola Willis has written a letter to Woolworths, and Foodstuffs' North Island and South Island arms, outlining her expectations. 

She says she's hearing of supermarkets charging more than the advertised price, and having specials and multi-buy deals that don't actually offer savings. 

Willis told Mike Hosking that's not good enough. 

She says supermarkets have publicly said again and again that they do everything they can to be good providers of service, but this doesn’t look like that.
