The nomination period for the Green Party's male co-leader contest has just closed and four candidates have been confirmed.
MP's Kevin Hague, Gareth Hughes and James Shaw as well as Green Party member Vernon Tava will run for male co-leader.
The position was vacated when current male co-leader Russel Norman announced he was stepping down at the end of May.
Over the next month the candidates will tour the country attending nine provincial meetings throughout the country.
The Green Party's electorate delegates will vote at the party's AGM on 30 May and the winner will be announced on the day.
Metiria Turei was the sole nomination to be re-elected as female co-leader.
