Support for Labour and its new leader has stalled in the latest ONE News Colmar Brunton poll, with neither the party or David Cunliffe making any gains over the last few weeks.
However, the centre left remains in a strong position thanks to gains for the Greens and a slight a dip in support for National.
National slipped two points to 45, bringing the gap between the two major parties to just 11.
The Greens climb one point to 13, while New Zealand First remains steady on 4.
Act and the Maori Party are stable on 1, while the Conservatives have backed up talk of being a potential coalition partner with a one point gain to 2.
When it comes to seats in Parliament, there's nothing in it. National has 58 seats and with one each from Act and United Future the centre right can muster 60.
But Labour's 43 seats plus the Greens 16 and Mana's 1 also gives the centre left 60.
The Maori Party with its three seats and New Zealand First could be the kingmakers.
But when it comes to preferred Prime Minister John Key still appears to have the golden touch, up one to 43%, while Mr Cunliffe hasn't built on his strong start and is unchanged at 12. Winston Peters is steady on 4%.
ONE News political editor Corin Dann says Mr Cunliffe has enjoyed the traditional honeymoon period since becoming leader and tonight's poll, while far from a disaster, suggests that is coming to a close and the hard grind of being opposition leader is just starting to kick in.
The poll surveyed just over 1000 voters and had a margin of error of plus or minus 3.1 percent.
