A derelict house in Mangere, Auckland is engulfed in flames.
A fire communications spokesman says there were reports of children around the house, but it has since been confirmed that no children were in the building at the time of the fire.
The fire has been upgraded to a third alarm, with 15 fire engines heading to the scene.
A fire communications spokesman says they are attacking the flames from the outside, because it's currently too dangerous to go in.
The cause of the fire is unknown at this point.
