An admission from the boss of Foodstuffs North Island, that changes are needed in the grocery sector

It comes after a Commerce Commission report found anti-competitive behaviour and excess profits were problems within the industry.

The supermarket chain now says it'll release its land covenants that stopped competitors setting up at certain locations.

It'll also support a consumer focused code of conduct and simplifying promotions and loyalty schemes.

Chris Quin says it was important to put these measures forward.

He says the changes being made will help to ensure Kiwis are getting the best value on goods.
