The three contenders vying for the Labour Party leadership will make their case to party members in Auckland on Sunday.
David Cunliffe, Shane Jones and Grant Robertson are on the second day of a series of campaign meetings around the country.
The trio will address Auckland party members at two meetings on Sunday afternoon - the first in South Auckland and the second in Western Springs.
About 300 party supporters attended the first meeting in Levin on Saturday.
Much of Mr Cunliffe's speech attacked the National Party as he urged members to choose a leader who could get the country out of its economic and social stalemate.
Mr Jones told the crowd he was capable of broadening Labour's appeal.
Mr Robertson pledged to knock over what he called the out-of-touch, crony-capitalist National Party.
