The National Party's support has remained steady despite its defeat in the Northland by-election, a new poll shows.
A TVNZ Colmar-Brunton poll released tonight showed National was backed by 49 per cent of respondents - no change since the previous poll in February.
Labour also remained steady on 31 per cent and Greens fell one point to 9 per cent.
New Zealand First rose one point to 7 per cent following leader Winston Peters' big win in the Northland by-election last month.
The poll was taken between April 14-18 and had a margin of error of 3.6 per cent.
