Back in 2002, supermarket chains Foodtown and Woolworths were allowed to combine into the group now known as Countdown. That consolidated the market down to a duopoly of the Australian-owned Countdown and the local cooperative of Foodstuffs, which owns Pak’nSave, New World and Four Square. A new report published by the Commerce Commission this week found the duopoly has used its market power to suck profits from either side of them in the grocery supply chain to make an estimated $430m a year in superprofits. To help unpack the report’s findings, Bernard talks to Sarah Balle, the founder of online grocery startup Supie.co.nz, about how hard it is going up against such a powerful duopoly, and Food and Grocery Council CEO Katherine Rich explains the fight supermarket suppliers face to be treated fairly.
