Colin Craig's Conservative Party has slumped to its lowest rating since it was founded, according to a poll to be released tonight.
The 3News-Reid Research poll has the troubled right-wing party polling at just 0.7 per cent - a collapse from its Election night high of 4.1 per cent.
The result comes after the controversy over Craig and his former press secretary Rachel MacGregor, which was followed by a protracted and confusing spat over party leadership.
Craig stood down as leader last month and held a press conference - with wife Helen by his side - admitting some of his interactions with MacGregor were "inappropriate". MacGregor resigned days before last year's election but details of what happened between the pair are suppressed by a confidentiality agreement.
Patrick Gower, 3News political editor said the result was the lowest the party had polled since appearing in the 3News poll shortly before the 2011 Election.
"The Conservative Party has been wiped out.
"Voters have deserted it in droves and Colin Craig will be wishing he was back in the sauna with David Farrier - that was his last happy political moment."
Craig's sauna appearance on TV3's Newsworthy was the "last straw" for many of the party's board.
The poll of 1,000 people has a margin of error +/- 3.1 per cent.
