A new opinion poll's showing a slip in support for the National Party.
The latest Roy Morgan poll has National on 43.5 percent support, a three point drop from a fortnight ago.
Labour is up two to 33 percent.
For the smaller parties, the Greens are down slightly to 11.5 percent, New Zealand First is up marginally to five percent, and the Maori Party scores 2.5 percent.
ACT and United Future barely register, while the Conservative Party, which is not in Parliament, has polled two percent.
