David Seymour says a new political poll shows Act and National aren't competing for votes.

The Newshub-Reid research poll has Labour down nearly 10 points to 43 percent, and National sitting at 29.

Act is at a record 11 percent.

Seymour told Mike Hosking the two parties now have enough support to win 51 seats in Parliament.

"We've gone up eight seats and there's only another ten before together we've got a majority. So it shows a change of government two years out is very possible."

Seymour's also ahead of Judith Collins in the preferred Prime Minister rankings on 8.6 percent compared to 8.2.
