Fire investigators are still working to figure out what caused a huge house fire in Whangarei overnight.
Emergency services were called to the address in Otangarei just after one o'clock this morning to find the home well ablaze.
The sole occupant of the house was initially unaccounted for, but fire staff didn't find anybody inside when they carried out a thorough search this morning.
A council building inspector will work with the fire crew, which remains at the scene.
