Hundreds of school students and supporters are set to join a climate change activist on his 100th day outside Parliament.
Ollie Langridge is the longest-running protestor to demonstrate outside the Beehive.
He says he won't stop until the Government declares a climate emergency.
Green Party co-leader James Shaw told TVNZ1's Breakfast today that Mr Langridge is helping raise awareness of climate change's impact on the planet.
"I've spoken to him a number of times and said to him, you know, 'Kia kaha, keep going', 'cause I think what he's done is – it's one of the really big things that's really helped to raise public consciousness around climate change over the course of this year," he said.
School strikers are expected to stand in solidarity with him on Parliament's lawn, while other students have planned events in their own communities.
