The signing of the Trans-Pacific Partnership prompted large protests but has had no dent in the National Party's ratings in the latest opinion poll.
National remains steady at 47 per cent support in the One News-Colmar Brunton poll taken in the aftermath of the signing of the controversial 12-nation trade pact in Auckland on February 5.
The worst news from the poll was for the Green Party, which dropped four points to 8 per cent. Its misfortune was New Zealand First's win -- Winston Peters' party went up one point to 10 per cent, propelling it ahead of the Green Party.
If that continues, NZ First would be the third-largest party in Parliament -- a long-held goal of Mr Peters, which raises the stakes for both National and Labour should his support be required for a future government.
NZ First would have the balance of power if the poll results were repeated in an election.
