The clear consensus among experts shows Darleen Tana is hanging on for their political life.

The former Green MP has filed an unprecedented injunction trying to prevent their former party convening a Special General Meeting this weekend.

ZB political editor Jason Walls says the Greens clearly didn't see this coming - but they're not too worried.

"They're clearly waiting to see what happens tomorrow... we all knew legal action was coming, but I was thinking the legal action would be around the actual legislation to do with the waka-jumping."
