ACT and National are on track to govern while Labour slumps to a new low, according to a new poll.

The latest Roy Morgan survey shows ACT has surged by 4 points to 18 percent, catching up to National's 31, down 2.5 percent.

Labour's taken a fall- their support dropped a further 2 percent to 24.

ZB senior political correspondent Barry Soper says the Roy Morgan poll is often dismissed in the lead-up to election night- but it's an accurate indicator.
