Co-leaders of the Green Party of Aotearoa New Zealand

The co-leaders of the Green Party of Aotearoa New Zealand are the dual highest-ranking members of the Green Party caucus, chosen by the party membership to represent the party. The current co-leaders are Marama Davidson and Chlöe Swarbrick.

Any member of the party can be a candidate for the co-leadership, even those that are not currently members of parliament, as long as they have five other party members willing to nominate them. From the creation of the role until May 2022, the party had a requirement that one co-leader be male and one co-leader be female. This was changed and now it is required that one co-leader be female and one co-leader be Māori. It is not required that these conditions be fulfilled by two different people.

Co-leaders are elected for one year terms at Green Party annual general meetings. Incumbent co-leaders are generally re-confirmed, though they are required to meet a 75% threshold of support in a vote amongst members. An incumbent co-leader has only been challenged twice for the co-leadership; in 2013 David Hay challenged Russell Norman, and in 2021 James Cockle challenged James Shaw. In both cases the incumbent won re-election. An incumbent has only failed to be re-confirmed without any challengers once; James Shaw in 2022 only garnered 70% of the vote in the first round. He was later re-elected.

The co-leaders comprise a quarter of the voting members on the Green Party's leadership team, known as Kaunihera (Council). The other members of the team consist of two Te Rōpū Pounamu kaiwhakahaere, two party co-convenors, and two policy co-convenors. The general manager of the party also sits as a non-voting member of the Kaunihera.

The role of Kaunihera, as stated by the party's constitution, is to "[m]onitor the performance of the Party against the [party's] Charter, Te Tiriti o Waitangi, the Long-term Strategy [and] any other Party strategies supplementary to the Long-Term Strategy".
