John Banks has confirmed he will not be having another tilt at becoming Auckland mayor.
In a statement to the Herald, Banks said he had made the decision that after "discussion and deliberation with colleagues, friends and family - and based on valuable political research".
Banks said that from the beginning of this year he had worked with "other like-minded people to approach and assist" other mayoral candidates to see if they were interested in running for the job.
"They all declined to do so, which led me to then explore my own possible candidacy," he said.
"This is because I have seen it as my duty to raise important issues and solutions to the various challenges that Auckland faces. As someone who cares deeply about Auckland, it has been frustrating to see inaction and bad decisions, and I am absolutely convinced there is a need for change in Auckland's leadership. Auckland is crying out for new ideas and better executive leadership."
