The Green Party says it remains highly unlikely it would support a National-led Government after the election.
The parties had a memorandum of understanding in the last Parliament and worked together on a home insulation programme.
[image:2735:third:right]National Party leader John Key says he does not know if the parties will work together again, but if the Greens were to hold the balance of power after the election in November he believes they would go with Labour.
Greens co-leader Metiria Turei says National would have to change a great deal of policy before her party would entertain the idea of supporting a National-led Government.
Ms Turei says areas where the parties have differences include state asset sales, welfare and the environment.
However, she says it is still possible the Greens could work with National again, for example, in an extended memorandum of understanding.
