Prime Minister John Key won't work with him, but more than one third of voters think the return of NZ First leader Winston Peters would be good for New Zealand.
Asked whether the return of Mr Peters to Parliament would be positive or negative for New Zealand, 56 per cent of respondents in the Herald DigiPoll survey said it would be negative and 36 per cent said positive.
About 8 per cent did not know.
There was also a significant increase in personal support for Winston Peters in the latest poll, whose stakes as preferred Prime Minister rose from 2.9 per cent to 5.2 per cent.
He outdid Labour leader Phil Goff among older voters - 14 per cent of those aged over 65 years named Mr Peters as their preferred Prime Minister compared to 13.2 per cent for Mr Goff.
