New World is asking its customers whether they'd be willing to pay to use plastic bags.
The supermarket giant's 'Bag Vote' campaign gives customers the choice of no charge, a 5c per bag charge or a 10c per bag charge.
Voting is open until October 8 and the results will be released on October 10.
The money raised by the bag charges will be donated by the Foodstuffs-owned supermarket to environmental causes, including the charity Seacleaners, which cleans up rivers and has been working with Foodstuffs on plastic bag reduction.
"We believe there is a real appetite for change on this issue," said managing director Steve Anderson.
"Our recent ban on plastic microbeads was met with universal support, as was the introduction of 100 percent recyclable meat trays. We're also rolling out electric vehicles across many of our stores and increasing access to soft plastics recycling around the country."
Since January 2016, North Island New Worlds have introduced a 5c rebate for customers who bring their own reusable bags, resulting in a 20 percent reduction in plastic bag usage.
Foodstuffs has not released figures on how many plastic bags it predicts will be saved, but may have an idea on the amount as Pak'n'Save - also owned by Foodstuffs - implemented a similar charge several years ago.
In 2009 The Warehouse introduced a charge for plastic bags, predicting a 20 million decrease in plastic bag usage in the first year.
