Support for the ruling National Party has dropped sharply in the latest Roy Morgan Poll, from 48.5% to 42.5%, taking it to its lowest level since October last year.
The results suggests that the turmoil that has struck National within the past week has had an impact.
The Green Party was the biggest beneficiary, rising to 14.5% from 11.5%, while Labour spiked to 31% from the lows of 28.5% previously. This would give a potential Labour/Greens coalition 45.5%.
The poll was conducted from April 21 to May 4 with 847 electors contacted both by landline and mobile phone.
This poll covers both the release of Labour's, generally well-received, monetary policy and the more recent high-profile struggles in the National ranks - the resignation from Cabinet of Maurice Williamson and the start of the latest difficulties engulfing Judith Collins.
The support levels for Prime Minister John Key’s current and potential coalition partners doesn't offer much encouragement for National either.
The Conservative Party dropped to 0.5% from 2%, while Maori Party was on 1% (unchanged), ACT NZ (0.5%, unchanged) and United Future 0.5% (up 0.5%).
Potential kingmaker Winston Peter's New Zealand First Party is still bubbling along reasonably at 6% (up 0.5%).
The Mana Party is on 1% (unchanged), while support for the Internet Party is now at a record high 1.5% (up 0.5%).
