Fifth-ranked Green MP Gareth Hughes has confirmed he's standing to become the party's male co-leader.
The 33-year-old, who's in his third term as an MP, says his candidacy is for a generational shift in New Zealand politics .
The male co-leader's job became vacant earlier this year when Russel Norman announced he was stepping down from the roll to spend more time with his young family.
West Coast based list MP Kevin Hague has already put his hat in the ring and is considered by some to be the front runner.
The party will decide on who the male co-leader is at its conference in late May.
