Conservative Party leader Colin Craig is delighted with the latest 3News-Reid Research poll which has his party's support nudging the 5 percent threshold.
Support for both the Conservatives and New Zealand First is up in the poll, at the expense of National and Labour.
The survey was carried out after the release of Nicky Hager's book Dirty Politics, which claims National ministers and staff have repeatedly smeared opponents by feeding damaging information to right-wing bloggers.
The poll has the Conservatives on 4.6 percent and New Zealand First on 6.3 percent. National and Labour fell to 45 and 26.4 percent respectively. The Green Party recorded 13.5 percent, while no other party got near 5 percent.
The Conservatives needs to win an electorate or 5 percent of the party vote to get MPs elected to Parliament. Mr Craig said he expected the party's support to rise further as the full impact of the Dirty Politics book comes through.
