The Greens have lost another chief of staff.
Andrew Campbell has announced his resignation after more than five years with the party.
He's been chief of staff since June last year, replacing Ken Spagnolo whose contract wasn't renewed.
Co-leader Metiria Turei says Mr Campbell, who was head of communications before becoming chief of staff, indicated his intention to leave the party after last year's election.
"He offered to stay on to oversee the transition to our new male co-leader James Shaw, and lead the internal change management process after James was elected," she said today.
"Andrew ran our communications through our two most successful election campaigns and has been a real asset to the party."
Ms Turei says Mr Campbell has overseen the recruitment process for a replacement chief of staff and an appointment will be made in the coming weeks.
