Whose supermarket policy is best?

All the major parties are promising action this election to shake up the supermarket sector. But which of their competing plans would actually bring down grocery prices?

There's one thing almost every political party seems to agree on this election: something needs to be done about New Zealand's supermarkets. But how far should the government actually go? 

National and New Zealand First want to split Foodstuffs into two competing businesses. Labour wants to separate the supermarkets' wholesale and retail operations. And the Greens want to establish Kiwi Mart, a publicly owned supermarket chain.

Which of these approaches is most likely to work? And if we’re serious about bringing down the price of groceries, are there other things we should be doing too?
