Labour Party delegates have today voted that a simple of majority of caucus members is all that will be required to trigger a leadership run-off.
An earlier proposal would have seen a two-thirds vote required to roll the leader, setting a far higher bar to topple the incumbent.
Earlier a vote giving the party the power to vote on the deputy leadership failed despite a strong number of speakers in support.
Among those urging the change were supporters of a gender balance in the leadership.
"We must have a woman and a man in our leadership," one speaker urged.
"It's of great concern we have two men at the top."
About 600 delegates have gathered in Auckland for the conference, which comes amid rumbles around the leadership of David Shearer.
