Key Points:

Support for the National Party is at a record high, according to the latest Roy Morgan Poll, released today.

The fortnightly poll puts National as holding a majority -- albeit slender -- the highest result recorded in the Morgan poll by either major party since the last election.

Of 853 respondents, asked who they would vote for if an election was held today, 50.5 per cent said they would vote National, up from 49 per cent last poll.

Labour is also up -- reaching 33.5 per cent after falling to a record low for the party of 32 per cent last time.

At the 2005 general election, Labour held a slight lead, with 41.1 per cent to Nationals 39.1 per cent, whereas at the 2002 election, Labour was well ahead on 41.3 per cent to National's 20.9 per cent.

Most of the smaller parties -- Progressive, New Zealand First, the Greens, and the Maori Party -- all recorded small drops of .5 or 1 per cent.

United Future and Act both recorded slight increases, both rising from 1.5 per cent last poll to 2 per cent this poll.

Of electors who said they were likely to vote (91 per cent), 6.5 per cent said they were undecided on who they would vote for.

The poll was conducted between May 21 and June 3.
