Police and emergency services are responding to reports a bushfire-fighting helicopter has crashed in northern Tasmania.

"Initial reports suggest a helicopter has crashed in a paddock while responding to a bushfire near Lebrina," Tasmania Police said in a statement on Monday afternoon.

"Details of injuries are not able to be confirmed at this stage."

Emergency services representatives are expected to hold a press conference later on Monday.

The bushfire at Lebrina, which sparked last week when a burn-off on private property got out of hand, has burned through more than 1500 hectares.
