The Government has expanded on how it will make supermarket giants open their wholesale arms to competitors.
It wants to improve competition in the sector by helping smaller retailers and new market entrants source and sell a wider range of groceries at better prices.
Commerce and Consumer Affairs Minister David Clark in late May said the Government would start working on a regulatory backstop to make big supermarket companies, like Foodstuffs and Woolworths, provide wholesale goods to competitors at a "fair price".
Today, he expanded on this commitment, saying "the existing duopoly will be required to negotiate wholesale offerings to their competitors on commercial terms".
"However if those prices are not what we would expect in a competitive wholesale market the new Grocery Commissioner will be able to impose additional regulation to force fairer prices.
