The latest Roy Morgan NZ poll shows a National/ACT coalition has a clear lead over the current Government.

The right-leaning coalition is up by 2.5 points to 47.5 percent, surging ahead of Labour's 26 percent and the Greens' 9 percent- a historic low for both parties.

ZB senior political correspondent Barry Soper says this is the beginning of the gap between the right and the left- with this poll representing a significant drop for Labour and the Greens.
