Winston Peters isn't giving up hope of being part of the next government.

The latest Taxpayers' Union Curia poll has New Zealand First up a whopping 2.5 points to 5.8 percent, giving it the numbers to return to Parliament.

But the poll also has National and Act on 61 seats, giving it the numbers to form a government without the party.

Peters told Mike Hosking he believes New Zealand First actually has a much larger share of the votes, and will have far more influence.

He says his own internal polling has New Zealand First on a level much higher than five percent.
