A former Green MP is pulling no punches with her opinion of James Shaw's leadership.

The Party was thrown into disarray on Saturday when the co-leader was not re-elected at its AGM.

Any potential contenders now have a week to confirm a challenge against Shaw, who's indicated he is likely to run again.

Former Green MP Catherine Delahunty told Kate Hawkesby he's not what the Greens are about.

She says the party needs someone in Parliament who's willing to stand up on vital issues, and not just be a lap dog to Labour.
