The Labour Party is accusing the Government of dillydallying on changes to the grocery market.
Economic Growth Minister Nicola Willis announced plans to speed up the supermarket consent process.
Labour Party Commerce spokesperson Arena Williams says Labour is working on a suite of changes, but she didn't reveal what they are.
She told Ryan Bridge the consenting changes could be used by the existing players.
Williams says it could create less competition and drive more profits to the duopoly.
