"Moving away from 350 million plastic bags takes a fair bit of work behind the scenes and by our team in our stores; these first stores will test our thinking, our training and our processes to ultimately help ensure a smooth transition for all of our customers and team when we make the change across the country."
Countdown isn't the only supermarket chain set to phase out plastic bags in New Zealand.
Last year, Foodstuffs also announced that it would move away from plastic bags at checkouts.
Foodstuffs also plans to discontinue plastic bags by the end of the year.
