A fire broke out at a Manurewa business today. St John was called to the fire on Great South Road at 12.25pm.
Firefighters are now working to extinguish the last of the fire dampen hotspots so they can get inside and establish how and why it started.
It is not thought to be suspicious.
The fire appears to have started in a ground level building in the two storey block - either in an Indian restaurant or massage studio.
It then spread up thorough the floor to the second level.
