Hon Dr DAVID CLARK: We've been very clear that the grocery sector needs to change so that competing retailers, whether they are independent dairies, smaller chains, or a new entrant, can offer a wider selection of products at competitive prices. That's why we've called on the supermarkets to open up their wholesale arms at a fair price to would-be competition—if not, the tool kit we've designed gives the Commerce Commission the authority to take action, including demanding retailers provide wholesale supply at certain times, price, and range.
