The National Fire Authority is yet to determine the cause of the fire that claimed the lives of three children in Bulileka, Labasa over the weekend.
NFA investigators are working with police to determine what may have caused the fire at around 8.35pm last Friday.
Three children aged 6, 9 and 13 years died after they were trapped inside the house.
The fourth child, an 11-year-old boy was able to escape but he sustained 10% burns.
The house belonged to a 43-year-old man and police say both parents were said to be at work when the fire started.
