Greens can't say how much cheaper groceries would be under KiwiMart plan

The Green Party has proposed KiwiMart, a government-owned supermarket chain costing $2.8 billion to buy 120 stores and two distribution centres. Co-leader Chlöe Swarbrick ruled out politicians setting prices and declined to say how much cheaper groceries would be. "Politicians are not economists," she said, leaving excess-profit definitions to the Commerce Commission. The duopoly holds 82 percent of the market.
