School Strike for Climate says it will hold its biggest strike yet as it takes on the Government over what it calls its "climate-butchering policies".
Students and adults are set to take to the streets on Friday, April 5.
Strikes will take place around the country, including in Ōtautahi Christchurch, Pōneke Wellington, Tāmaki Makaurau Auckland, Ōtepoti Dunedin and Kirikiriroa Hamilton.
It's unclear how many are expected to turn out, but previous strikes have seen over 38,000 people.
In a statement on Sunday, School Strike for Climate's Ōtautahi Christchurch arm said the aim was to "bring about action on intersectional climate and social justice issues in Aotearoa".
"As the current government proposes climate-butchering policies like the repeal of the ban on offshore oil and gas drilling, as well as a possible treaty referendum, and in the wake of racist policies such as the recent abolishment of Te Aka Whai Ora, this is an especially important time to make our voices heard. We plan to see the biggest strike mobilisation to date."
The aim was to drive both council and central Government to take action on climate and social justice issues.
"This Government's anti-democratic, racist, ecocidal conduct makes me sick. Aotearoa is better than that and this strike aims to send that message of kotahitanga in a way they can't ignore," School Strike for Climate Ōtautahi's Aurora Garner-Randolph said.
Demands from the Christchurch arm were for the Christchurch City Council and Government to count international transport emissions, keep the oil and gas exploration ban, honour the Treaty, and keep the ban on live exports.
It's also calling to "free Palestine", saying it wanted to "withdraw NZ forces in Yemen" and expel the Israeli ambassador.
The Government has said no NZ Defence Force personnel will enter Yemen.
"Our climate situation is only getting worse, and we need the Government to be taking urgent and drastic action to move us forward," School Strike for Climate Ōtautahi's Bugs Sullivan said.
"For them to be planning policies that actively take us backwards should be out of the question."
