A spokesman today said that a fire investigator had been called to the scene but was yet to arrive.
The house belonged to the grandparents of a boy at Ngākuru School and the school was focussing on making sure he was okay while the family sorted out what they needed to, principal Rachel Weinberg said.
When Weinberg heard about the fire she got in touch with the boy's mother to make sure everyone was safe and offered support.
The school would put their thinking caps on to see what they could do to support the whanau and help in "whatever way we can".
She said the mother had put a post on a community page thanking everyone for their offers of support.
Weinberg said the small community was "really special" and believed many people offered to provide anything they needed including houses to stay in temporarily and furniture.
"Small communities like this really rally around when things like this happen."
