Firefighters are trying to confirm if anybody was stuck inside a building on fire on the West Coast this morning.
The fire broke out on a property south of Fox Glacier this morning.
A Fire Service southern communications spokesman said the fire at a building, probably a shed, was "well-involved" when firefighters arrived just before 7am.
Firefighters were initially told a person might be inside the building.
"At the moment the brigade is still trying to verify those claims."
