A new plan is being touted as a way to fast track shaking up the grocery sector. 

The New Zealand Initiative is proposing allowing new entrants to enter the market, rather than forcing any break-up of the existing supermarket companies. 

It outlines the need for fast track plans for rezoning, consenting, overseas investment clearance, and a more neutral stance from the government. 

Chief Economist Eric Crampton told Mike Hosking a new entrant should get a head start. 

He says within five years the government would find out whether planning barriers are what's held companies back. 

Foodstuffs and Woolworths are both members of the New Zealand Initiative.
