Kiwis are constantly wondering why their groceries are so expensive. 

The Green Party is the latest to promise a fix in the way of a members bill aimed at banning price gouging by the supermarket duopoly, which has a whopping 82% market share. 

New rules would aim to prohibit supermarkets from charging prices that are excessive when compared to the cost of supplying groceries. 

Breaches could see a company fined up to $10 million or 10% of turnover. 

But, what constitutes “excessive”? And how would it be policed? 

Today on The Front Page, Green Party co-leader Chlöe Swarbrick is with us to tell us how it would work.
