Labour and the Greens to team up for key speech

In a symbolic and radical move, Labour and the Green Party will join forces for the 2017 State of the Nation speech.

Labour leader Andrew Little and Greens co-leader Metiria Turei will jointly deliver the speech on January 29.

In an election year, it's an unprecedented move for two parties to present such a speech together. Labour and the Greens announced last year they'd work together to bring down National.

Traditionally each party delivers its own state of the nation speech to highlight their priorities for the year ahead. 

Meanwhile,the Labour Party meets on Tuesday at Breckenridge Retreat in Martinborough for its first caucus meeting of 2017.

The party will plot its strategy for the Mt Albert by-election and the general election.

Jacinda Ardern is standing for Labour and Julie Ann Genter for the Greens, while National isn't standing a candidate.
