National's retained its top spot in the latest 1News Kantar Public Poll - while Labour has suffered a further drop in popularity

National is steady on 39 percent and Labour has fallen by two points to 35 percent.

The Greens have enjoyed a one point bump in popularity to 10 percent - and Act is down one - to just seven percent.

But Jacinda Ardern's still the preferred Prime Minister -- but is now only eight percent ahead of National leader Chris Luxon.

How that translates into seats is down to the wire.

National and Act together would have 60 - while Labour and Greens would have 58.

But if Te Pati Maori joins the latter - a Labour Greens Maori Coalition would also have 60.
