"My priorities were to have the leadership process completed and the review on track. Both of those are in place."
She said having the handover now rather than waiting until the November annual conference would mean her successor could be in place in time to deal with the review's outcomes. "The people who implement that plan should be those who develop it."
Ms Coatsworth oversaw significant changes in the party including the change to the new system for electing a leader which gives the party membership and union a vote. Prior to that the leader was chosen by caucus alone. The impact of that change is significant - in the two leadership contests since then neither of the eventual victors, David Cunliffe and Andrew Little, have been the caucus top pick.
However she and Labour's party machinery have come under fire from some close to the party, including former President Mike Williams, for neglecting basics such as fundraising and getting bogged down on side issues such as the quota for women.
Asked if she believed the criticism was valid, Ms Coatsworth said it had been a challenging time for the party but she was confident new leader Andrew Little would be able to take the party forward.
