Students had planned to strike on September 4.
Last year 170,000 students took to the streets to demonstrate. Several thousand congregated in Christchurch's Cathedral Square.
The movement has maintained momentum.
The School Strike 4 Climate Christchurch committee has been meeting every Thursday to plan and prepare.
Organiser Ciara Foley was unable to say when the strike would occur, but hoped to provide an update within a few days.
Under Level 2 restrictions, mass gatherings are limited to 100 people. At Level 3, gatherings are limited to 10 people.
Foley said the strike was crucial in raising morale among young activists, particularly after a challenging year.
"We hope to get climate change back into the front of peoples minds and actions," Foley said.
"The window of time we have to act on climate change is rapidly closing, so we needs to bring it back to the forefront of the agenda; we need both local and national government to include it in every decision made "
School Strike 4 Climate is caling on the government to invest in a Green Covid Response and that it works toward transitioning all workers into unsustainable jobs. It is also urging all political parties to adopt strong climate policies that reflect the urgency of the current crisis.
