Auckland firefighters are at the scene of a factory blaze in Papatoetoe that broke out at around 4am.
It's at the Crow Refractory - a company that makes boiler liners, and was the scene of a much larger blaze late last year.
The fire is just about out - it's been confined to an area in the middle of the factory.
An extremely long ladder is being used to get over the seat of the fire.
Investigators are attending.
