Calls for certainty from the supermarket sector as Economic Growth Minister Nicola Willis weighs more action.  

She's introduced fast track consenting to encourage new players into the market. 

Willis says she's looking carefully at the idea of breaking up the duopoly.  

Foodstuffs North Island Chief Executive Chris Quin told Mike Hosking the future of their business needs clarity on what regulations will be put in place.  

He says the individual owners are scratching their heads wondering what's going to happen.  

Quin also believes the amount of competition already in the market may be higher than people realise. 

He says 30% of the retail grocery market is third players in Auckland and 18% nationwide.
