Two new political polls out on Sunday have National retaining a commanding lead over the Labour Party.
The TVNZ and TV3 polls were taken in the wake of Labour MP Chris Carter's attempt to destabilise the leadership of Phil Goff.
Labour strategists may have feared a fall in the polls, following Mr Carter's attack on Mr Goff.
But the two polls show Labour's vote holding up, and even increasing slightly.
The 3 News-Reid Research poll has Labour steady on 30.6% to National's 54.5%, while the One News Colmar Brunton poll shows Labour up two, at 35% with National on 49%.
Both polls also record a rise for Mr Goff as preferred Prime Minister, up 2-points to 7.4 and up 3-points to 9% respectively.
But John Key remains well ahead in the preferred prime minister stakes on 49% in the 3 News poll, and 45% in the One News poll.
Of the minor parties, only the Greens top 5%, on 8.5% and 7% respectively.
Both polls surveyed a 1000 people, and have margins of error of about 3%.
