The Prime Minister doesn't care a new poll's scored his Party at its lowest in more than a year

The Taxpayer's Union-Curia poll puts National down 4.1 points on September - to just under 35 percent.

Labour rose 3.6 points, to 30 percent.

As preferred Prime Minister - Chris Luxon is down five points - on 27.7 percent - and Labour's Chris Hipkins has risen 4.3 - to almost 17.

Luxon says up or down, it doesn't matter to him.

He says he's focused for delivering for New Zealanders and he has a plan, which is starting to work.
