Labour's controversial stance on foreign buyers has failed to earn the party a significant lift in the polls.
The latest TV3 Reid Research poll showed Labour's popularity was almost unmoved, rising by 0.7 percentage points to 31.1 per cent.
The poll was taken after Labour reignited the debate on foreign ownership by releasing data which showed nearly 40 per cent of house sales in Auckland went to people with Chinese surnames.
National also moved only slightly in the survey, rising by 0.6 points to 47 per cent.
The Greens remained nearly unchanged on 11.4 per cent, as did New Zealand First on 8.4 per cent.
