Politics commentators Matthew Hooton and Neale Jones talk to Kathryn about the results of the latest Newshub Reid-Research, which show that Labour leader Jacinda Ardern could comfortably lead alone. The poll has Labour on 56.5 percentage points - up 14 - while National slumps down 12.7 percentage points to 30.6. The Greens sneak in just above the 5 percent threshold while New Zealand First falls to 2.7 percent.

The latest Newshub Reid-Research poll puts Simon Bridges' leadership on notice, and National Party itself in an unenviable position, say commentators Matthew Hooton and Neale Jones.

The poll shows Labour leader Jacinda Ardern could comfortably lead alone with Labour on 56.5 percentage points - up 14 - while National slumps down 12.7 percentage points to 30.6.

A "hunk" of National MPs are reluctant to be responding to polls, Hooton says.

"Their views on this is what's going to decide Simon Bridges future."

The numbers are even worse if you put them together with voting blocs, Neale Jones

"The governing parties are on 65 percent and National and ACT are on 32. That's more than double.

"National has had a pretty solid base of at least 40 percent ever since they consolidated the centre right vote under Don Brash all those years ago. This poll suggests that Ardern is carving deeply into National's core voter support."
