Finland votes in elections for new regional assemblies in January, and MPs will be among those who run for office.
Nearly half those asked by Yle said they had not yet decided, while almost one in three said they would run.
Some 115 MPs answered Yle's survey on candidacies for the new assemblies, which will decide health and social care policies.
Opposition MPs were more likely to consider a tilt at regional office than those in government, and Finns Party MPs were most likely of all to say they will run in the regional elections.
Ten Finns Party MPs said they would run, with four saying no and four still on the fence. They were the only party to have a majority of legislators declare they plan to run.
MPs declining to enter the race gave different reasons, including demands on their time in parliament and local councils (Finnish MPs often hold local councillor positions in their home municipalities), as well as potential conflicts of interest.
Others said they were keen to be on the spot to help make decisions on important matters.
The new bodies will be elected in 20 of 21 new regional authorities created to manage social and healthcare services. Helsinki will form one of these regions, with the local council taking the decisions without a need for new elections.
The elections are slated to take place on 23 January, with eligibility criteria the same as for municipal elections. That means voters do not need Finnish citizenship to qualify, with residence of two years sufficient for those from outside the EU and just 51 days required for people from EU countries, Iceland or Norway.
