Polls from the Herald still has the Nats ahead

It appears that the transrail share gaffe by Key didn't impact on voters .... They still trust him.

The political divisions and allegiances triggered by the furore over secret donations to New Zealand First and leader Winston Peters have had little effect on party standings in the latest Herald-DigiPoll survey.

Support for National, which has said it would not work with New Zealand First after the election, has risen slightly, by 1.4 percentage points, to 51.4 per cent of decided voters.

This would give it 68 seats in Parliament - enough for it to govern without a coalition partner.

Labour, which aligned itself with Mr Peters, is down 0.6 points to 35.7 per cent.

New Zealand First is up by 0.7 but to only 2.8 per cent - not enough for it to stay in Parliament after the November 8 election without winning an electorate seat.

The Green Party has slipped under the 5 per cent threshold, and at 4.9 per cent would also be a casualty without an electorate.

Mr Peters' standing in the preferred Prime Minister poll has fallen, by 1.6 points.

But Prime Minister Helen Clark and National leader John Key have also slipped.

The two main-party leaders are close as preferred PM, however, with Helen Clark down 1.9 points to 43.1 per cent and Mr Key down 1.1 to 45.5 per cent.

Their ratings have varied little since May.
