Support for Tasmanian Premier Peter Gutwein has surged during the coronavirus pandemic, according a new poll.
An EMRS survey released on Tuesday shows the Liberals' Mr Gutwein has 70 per cent backing as the island state's preferred leader.
It is a substantial rise from the 39 per cent figure recorded in a March poll, when he trailed Labor's Rebecca White by two points.
Support for Ms White has fallen from 41 per cent to 23 per cent over the same period.
Mr Gutwein became Tasmania's 46th premier in January during the early stages of the pandemic, following the shock mid-term resignation of Will Hodgman.
Liberal government backing is at 54 per cent, an 11 per cent rise from the March poll.
Labor sits at 24 per cent, a drop of 10 per cent from March, while the Greens are steady at 12 per cent.
"The latest poll results coinciding with the period of the COVID-19 impacts certainly show a sustained vote of confidence in the government's performance and leadership over recent months," EMRS research manager Paul Jamrozik said.
Tasmania was in March the first jurisdiction to close its borders and has recorded just two COVID-19 cases in about three months.
The poll surveyed 1000 voters in late August.
