A state government's post-election honeymoon may be over but voters aren't contemplating divorce in the lead up to a key vote over a contentious football stadium.
Support for Tasmania's Liberals dipped four per cent in the past three months, but if a new election were to be held they would still likely retain power, the latest EMRS survey shows.
Labor has gained one per cent support, the Greens' popularity has improved by four per cent while independents stayed the same.
The poll shows the Liberals at 34 per cent, Labor on 25 per cent, the Greens on 17 per cent, while independents remain at 19 per cent.
Premier Jeremy Rockliff's popularity dropped from +18 favourability down to to -1, while Labor leader Josh Willie suffered an eight-point hit to be -4.
"These numbers suggest that Premier Rockliff's post-election honeymoon may be over," EMRS managing director Mary Massina said.
"However, with most of the gains going to the Greens and the Labor vote continuing to languish in the mid-20s, an election now would likely see the re-election of the Liberals."
Some 1000 Tasmanians took part in the poll last week.
The state election on July 19 delivered a hung parliament and Mr Rockliff won power following negotiations with crossbenchers.
On Sunday, thousands of people took to the streets to urge undecided politicians to turf plans for a contentious AFL stadium at Macquarie Point in Hobart.
The state's upper house will next week vote on whether to build the $1.13 billion roofed stadium, the key condition of whether the Tasmania Devils enter the AFL and AFLW in 2028.
A pro-stadium demonstration will held on Sunday, days before the crucial vote.
A planning body report previously recommended the venue should not be built over concerns it would add to the state's growing debt.
