New Zealand First leader Winston Peters says the public should be prepared for a shock when the election results come in on Saturday night.
Mr Peters spent his last day of campaigning in Rotorua, where his party's list MP Ron Mark is standing, and in Tauranga where Mr Peters has been fighting to regain the seat he lost in 2005 to National's Bob Clarkson.
None of the four polls released in the past 24 hours show New Zealand First crossing the 5% party vote threshold needed for it to return to Parliament without winning an electorate.
Speaking in Rotorua, Mr Peters said polls which showed his party was failing were wrong and commentators had been underhand and negative.
He said in 2002 the polls showed his party well under the 5% threshold, but the actual results gave him 13 MPs.
