A view higher than average grocery prices show something's clearly wrong with our grocery sector

The Commerce Commission's revealed our prices are the fifth-highest in the developed world.

It highlights the market doesn't support new players and major supermarkets continue to wield power over smaller stores.

Grocery policy expert Ernie Newman says there's no good reason for us to pay so much.

He says for a country that's an extremely efficient food producer, we should be paying way below the OECD average - which we used to.
