Jennifer Howard, one of five former cabinet ministers who challenged Premier Greg Selinger's leadership last year, says the party has put its disagreements behind it.
Education Minister James Allum says caucus has learned that campaigns matter and can turn around political fortunes.
He also signals that an advertising blitz will come this fall, ahead of the provincial election slated for April.
Allum says the NDP has an obligation to tell people what it stands for and contrast it with the position of the Opposition Progressive Conservatives.
It was at last year's caucus retreat that the internal revolt erupted, leading to a leadership challenge that Premier Greg Selinger barely survived.
The NDP has been showing below 30 per cent in the polls — well back of the Tories — since the government broke a promise and raised the provincial sales tax in 2013.
