Labour Party leader David Cunliffe is defending his performance in the election campaign, saying his level of support compares favourably with that of past Labour leaders, Radio New Zealand reports.
Cunliffe will formally resign from the job at his party's caucus this morning, but has already said he will run again.
So far, only Cunliffe and senior MP Grant Robertson have said they will contest the leadership.
In the election Labour got just 24.7 per cent of the vote, its lowest since 1922, but Cunliffe said his own ratings were not so bad.
“The voters of New Zealand have shown that my level of preferred PM ratings was around about the same as Helen Clark in 1996, on many measures a little better than Phil Goff in 2011, and it is at the end of the day a matter for the party to decide.”
