On the poll's numbers, Labour could not form a government, even adding their 36 seats with 13 from the Greens.
The last 3 News Reid Research Poll before the election also shows National able to govern alone.
The party's 50.8 per cent support would give them 65 seats.
Labour drops back to 26 per cent, and the Green Party record their best ever result, 13.4 percent, or 17 seats, said TV3.
NZ First, with support dropping to 3.1 percent, is well short of the five percent mark needed to make it into Parliament.
The Conservative Party is at 1.8 per cent, the Maori Party is on 1.5, Mana 1.1 and ACT 1.0, meaning it must win the Epsom seat to survive.
The United Future Party failed to register for the seventh consecutive poll.
Another poll will appear in tomorrow morning's New Zealand Herald.
