Air pollution in parts of town caused by smoke from home fires is still a worry for Masterton District Council.
At its recent meeting, the Environment Task Group identified the problem as a major issue as air emissions were above the accepted level.
Environment and Planning manager Sue Southey has suggested the council concentrates on getting remaining houses using old-style woodburners to either change to modern woodburners or to heat pumps.
Councillor Chris Peterson, who chairs the task group, said a survey was being done on that very issue.
He expected results of the survey to become available in time for the task group's September meeting.
