Green MP Elizabeth Kerekere will not be standing for the co-leadership of the party, paving the way for James Shaw to return to his role.
Kerekere had previously signalled she would consider standing and had not publicly offered her support to Shaw.
In a new statement, issued via the Green Party, Kerekere said she has decided not to run for the top job.
“Like many of my fellow MPs, I received many messages following the AGM asking me to stand and some members asking me to support other candidates,” she said.
“I have taken the time to reflect and discuss with my whānau, party members and Caucus colleagues once we were all in a clearer head space before making any decisions regarding the outcome of recent events.”
Shaw has received few outright endorsements from within his own caucus, but no one has so far said they will stand against him. Marama Davidson and Eugenie Sage were first to say they backed Shaw for the job.
In her statement, Kerekere said the Green Party needed to listen to its members who had signalled “a desire for accountability” from the co-leaders. “I believe this election presents an opportunity for any and all candidates who may run to clearly state the progressive, left-wing values which are the only way to achieve the critical system shifts we need to uphold Te Tiriti o Waitangi, address climate change and inequality, and protect biodiversity,” she said.
