Latest political polling paints a concerning picture for the National Party, with it slipping to 28.4% support in the March Taxpayers' Union-Curia Poll.
It comes as rumours circulate around political circles about leadership speculation in the party.
It gives the left-block a projected 61 seats if the results were to be reflected at the election, which is just enough to take power, against the right-bloc's 59 seats.
The poll suggested Labour support of decided voters was at 34.4%, up 0.3 percentage points and National was down 2.9 percentage points to 28.4%.

The Green Party was at 10.5%, while NZ First dropped 0.8 percentage points to 9.7% and ACT rose by the same percentage points to 7.5%.
Te Pati Māori was at 3.2% and 'other' was at 6.2%. Of those asked, 5.1% were undecided.
Translated to seats in Parliament, Labour had 44, National 36, the Green Party and NZ First both had 13, ACT had 10 and Te Pati Māori had 4.
For preferred PM, Labour leader Chris Hipkins was up 4.7 percentage points to 22.7% and Prime Minister Christopher Luxon was down 1 percentage point to 21%.
The poll was taken between March 1-3 of 1000 New Zealanders and weighted to the adult population. The maximum margin of error was +/- 3.1%.
