There’s potential for a more radical leadership of the Greens in the wake of co-leader James Shaw's resignation. 

Shaw's announced he'll step down in March but will remain an MP for the time being to support his Sustainable Environment Bill. 

Green Party rules state that a woman and a Māori person must be in leadership roles, but with Marama Davidson covering both criteria, the floor is wide open. 

Former MP Catherine Delahunty says some members are looking for a genuinely radical approach from the Greens. 

She says we could see a more authentically strong environmental position, which won't be so popular with the business sector, but at the end of the day that's not the Greens job.
