The Green Party of Aotearoa New Zealand male co-leadership election, 2015 was held to determine the future leadership of the Green Party of Aotearoa New Zealand. The election was won on the first ballot by first term List MP James Shaw.

In January 2015 Russel Norman announced his intention to stand down as co-leader of the Green Party.^[1] This triggered an election to fill the now vacant male co-leadership.

The voting was conducted via an STV vote by 127 party delegates from electorates across the country. The following table gives the ballot results:^[3]

Shaw became the Green Party's third male co-leader and joined Metiria Turei in leadership duties. Shaw set himself the goal of making the Greens "more like modern New Zealand" and an ambitious target to expand the party membership to over 20,000. At the time the party had around 6000 members and he wished to double the membership of the party in a year, then double it again the following year.^[4] By the time of the 2017 general election, Shaw was the sole Green Party leader; Turei resigned her co-leadership following public scrutiny of her announcement that she had committed benefit fraud in the early 1990s.^[5]

Hague later admitted that losing was a "blow" and when he was approached by Forest & Bird, he decided to resign from the House of Representatives and take up the CEO role for that organisation instead. His resignation was announced in September 2016.^[6] Vernon Tava later quit the Green Party altogether believing the party had lost its way from environmentalism and was becoming "too socialist". He joined the 2017 campaign team of National's East Coast Bays candidate Erica Stanford.^[7]
