State premiers handled the New Year's bushfire crisis better than Prime Minister Scott Morrison, according to voters in a new poll, which has revealed a growing shift in attitudes towards government action on climate change.

More than a third of voters surveyed "strongly disapproved" of Mr Morrison's handling of the bushfire crisis, while more than 20 per cent disapproved, leaving him with a net approval rating of just 32 per cent.

In contrast, Victorian Premier Daniel Andrews had a net approval of 58 per cent for the way he reacted to the fires which devastated East Gippsland and the state's alpine region, with 55 per cent of voters approving of NSW Premier Gladys Berejiklian's handling of the fires which killed 25 people across that state.

Mr Morrison faced fierce criticism over the past month for a decision to take a week-long holiday to Hawaii during bushfires across the east coast.
