Labour is ahead of National in the third consecutive poll to be released in the last two weeks.
The Opposition party is at 37 per cent in the new Bauer Media Insights IQ poll of 1528 Kiwi voters, which has National sitting at 34 per cent this afternoon.
These results come less than a day after the release of the latest One News Colmar Brunton poll, which last night put Labour at 43 per cent and National at 39 per cent.
Another One News Colmar Brunton poll from late last month had Labour at 43 per cent, with National slightly behind on 41 per cent.
According to Bauer Media's poll a significant 10 per cent of voters are still unsure of which party would get their vote - unlike other polls it collected "don't knows" separately.
It also puts the Greens up fractionally compared to earlier polls - at 6 per cent - and New Zealand First down slightly on 7 per cent.
Other minor parties - Top, Act and Maori - are at 2 per cent, 1 per cent and 1 per cent respectively, according to the Bauer Media poll.
Meanwhile, Labour leader Jacinda Ardern holds a commanding lead in the preferred prime minister stakes over her National Party rival Bill English, according to the poll - 46 per cent to 36 per cent respectively.
But nearly half (47 per cent) of voters thought New Zealand's economy would do better under Bill English. Only 29 per cent said they thought the country was more likely to financially thrive under Jacinda Ardern.
