Two opinion polls released today have boosted National's chances of holding a majority in the next Parliament but they also added to the confusing picture of voter intentions.
The only consistent factor in the last four polls has been increased support for the Greens, while Labour has been up and down.
This morning a New Zealand Herald DigiPoll put National's party vote support down one point to 50.4 percent, which would still be enough to win 63 seats - an outright majority - on election night.
Labour was up 1.3 points to 37 percent and the Greens gained half a point to reach 5.4 percent.
A few hours later a New Zealand Morgan poll presented a different set of results - National up 2.5 points to 43 percent and Labour down 5.5 points to 32 percent.
The Greens shot up to a remarkable 11.5 percent, which appeared to be linked with Labour's decrease.
Although the Morgan poll showed National holding an 11 point lead over Labour, the centre-left and centre-right gap was much smaller.
Labour and the Greens together captured 43.5 percent of the party vote and National plus the ACT Party stood at 46.5 - a gap of only three points.
A TV3 poll last night showed the centre-right and the centre-left both holding 59 seats, with the Maori Party in a position to decide which of the main parties formed the next government.
New Zealand First dropped 0.7 of a point in the Herald poll and was on only 2.1 percent support, but the Morgan poll showed it gaining half a point to 4.5 percent - just half a point short of the 5 percent it needs to win seats.
