Labour leader David Cunliffe says a government he leads would get unemployment down to 4 per cent by the end of its first term.
It currently stands at 6 per cent, or 147,000 according to the official measure, the Household Labour Force Survey.
Mr Cunliffe also reiterated Labour's pledge to run surpluses as National is planning to do, unless faced with another global downturn or domestic disaster.
The pledge to get the employment rate to 4 per cent would mean 20,000 fewer unemployed people, based on today's employment statistics.
Treasury's most recent projections for the unemployment rate for the years ended June 2017 is 5.2 per cent and for 2018 it is 5.1 per cent, but revised projections will be announced on Thursday in Bill English's sixth Budget.
