Giving the Commerce Commission more powers, particularly to request and get information from the supermarkets, will assist in monitoring and enforcement. And that's been a really useful addition that the select committee has made to the bill. The Resource Management Act (RMA) has sought to prevent trade competition being used as an argument by supermarkets against their rivals seeking a land use consent to establish a new store. There've been changes to the Act to try and strengthen these provisions because of the frustration at how rival operators would attempt to tie up the establishment of a new supermarket by objecting to the resource consent, but they haven't been totally effective in ensuring that the other member of the duopoly couldn't make submissions because the courts did look at the indirect effects in terms of the retail distribution effects. So the RMA hasn't been the answer, and that's why we have needed this bill.
