The National Party has continued to surge ahead in popularity in the latest Roy Morgan opinion poll, while Labour has slumped to its lowest level of support since David Cunliffe became leader.
The latest poll of 859 electors conducted through both landline and mobile telephone from February 3 to February 20 shows National moving from 47% support in the previous poll to 48%, which is its highest reading since July last year.
Conversely, Labour's dropped from 33% to 30% in the latest poll and that's a lower level of support than the party was on when David Shearer stood down as leader on August 22 last year - though Labour's support did dip as low as 26.5% in April 2013. Immediately following Cunliffe's election as leader in mid-September, Labour enjoyed 37% support.
The Greens, having slipped from 14.5% support late last year to 11% in the last poll have now moved back up to 12%.
The latest poll result leaves National tantalisingly close to being able to govern alone - should the results be converted into election results.
However, in terms of potential coalition partners for National, it was again a mixed story. Colin Craig's Conservative Party, being groomed as a potential partner, has slipped again and in the space of a month has gone from 2.5% support to just 1%. Meanwhile ACT, which recently elected Jamie Whyte as new leader, has bounced back from zero in the last poll to 1% support - actually its highest reading since October.
But the Maori Party has slipped again from 1.5% to just 0.5%, putting it behind the Mana Party, which was steady on 1%, though Peter Dunne's United Future has re-emerged from zero to 0.5%.
If National can't make it into Government on its own, this poll's results suggest an increasing possibility it might need to talk to Winston Peters and his NZ First Party. Peters and NZ First have moved up to 5.5% support from 4.5% support in the last poll.
