The Tasmanian Liberals have maintained a strong lead in the latest opinion poll, despite the State Opposition gaining ground.

Key points: Support for Liberal party falls two per cent to 46

Support for Liberal party falls two per cent to 46 Support for Labor party increases two per cent to 27

Support for Labor party increases two per cent to 27 Preferred premier: Hodgman down 4 to 52 per cent, Green up 2 to 21 per cent

The latest Enterprise Marketing and Research Services (EMRS) survey of Tasmanian voting intentions shows a 2 per cent increase in support for the Labor Party since November to 27 per cent, excluding undecided voters.

They're still trailing the Liberal Party which was the first choice of 46 per cent of those surveyed, down 2 per cent.

State Opposition Leader Bryan Green described the improvement as a consolidation.

He had been encouraged by the response to this week's Labor tour of the state.

"We've had a terrific response from people and I'm galvanised on continuing the work to ensure we're in a good position leading up to 2018 to provide an alternative government," he said.

Mr Green's personal approval rating improved from a low of 19 per cent by two per cent, while Premier Will Hodgman's popularity dropped four points.

Support for the Greens also dropped by two per cent to 18 per cent.

Greens Leader Cassy O'Connor said the changes in party support were within the margin of error, but pointed to a 4 per cent drop in the Premier's popularity.

"The most telling number was the decline in support for Will Hodgman as preferred premier and perhaps that points to a feeling amongst Tasmanians that he's not showing leadership in these very difficult times," she said.

Government Minister Rene Hidding said he did not think the poll was significant.

"Generally Tasmanians think very highly of the Premier and so they should," he said.

The results taken from a survey of 1,000 adult Tasmanian residents has a margin of error of 3.1 per cent.
