The Green Party and New Zealand First are down by half in the second poll since Jacinda Arden took over as Labour leader.
The latest UMR poll puts Labour up 13 points to 36 percent while the Greens have slid to 8 percent from 15.
The poll has National on 43 percent – up from 42 and New Zealand First on 8 percent – down from 16.
The results follow the Newshub / Reid Research poll out last night which put Labour up nine points to 33 percent since Ms Ardern took over as leader and the Greens down more than four points to 8 percent.
It had National down slightly to 44 percent – the lowest it has registered in this poll in the past 10 years – and New Zealand First was down more than three points to 9 percent.
Both polls were taken before Green Party co-leader Metiria Turei’s resignation.
Stephen Mills from UMR – which does polling for Labour – told Morning Report its latest survey was completed on Sunday night so also didn’t capture the withdrawal of Green MPs Kennedy Graham and David Clendon from the party’s caucus.
Mr Mills said in addition to taking votes from the Greens and New Zealand First Ms Ardern had likely taken some younger female support from National.
