New Zealand First is heading into the election with a plan to break up the supermarket duopoly.
If re-elected, the party's promising to split Foodstuffs into two nationwide co-operatives - one for New World and Four Square, and the other for Pak'nSave.
Consumer NZ says the current Government's efforts to encourage a third player into the market have largely been unsuccessful.
Head of Advocacy and Research, Gemma Rasmussen, has raised questions over this plan - and indicated it might not be the best solution to rising food prices.
