Labour Party members have reacted with surprise at leader David Shearer's decision to step down, but fellow MPs described him as a "nice guy" whose time was up.
The party took some consolation from the fact that Mr Shearer went quietly and was not ousted in a bloody coup.
Deputy leader Grant Robertson said he had only found out about his decision mid-morning - a few hours before Mr Shearer called a press conference to announce his plans.
Former Labour candidate Josie Pagani said she was surprised and saddened that Mr Shearer had not lived up to his promising potential.
"He came in on such a ticket of change and a feeling that this was a new beginning after a pretty dismal electoral defeat. And we had a lot of hope about that. And it's just been a sort of slow decline of really believing that could be delivered."
