Campaigners have taken their call for a ban on plastic bags to the steps of Parliament.
More than 65,000 New Zealanders, including high-profile supporters Helen Clark and Sam Neill, have signed a petition calling for a regulatory ban on single-use plastic bags.
The petition has been marched through the streets of Wellington to reach the Beehive.
Supporters holding banners and dressed as plastic bags and penguins have joined the hikoi, chanting "Ban the bag Jacinda".
