The woman woke up her two teenage children, sleeping in another bedroom, and was able to get the younger ones out of the house, Mr Bootten said.
"The [children] already did the Firewise [programme] through their school and had practised learning it for real. They got down below the smoke and went to the meeting point at the letter box, which had been pre-arranged, and then mum got one of the little ones to call the fire brigade, so that worked extremely well."
Fire crews from the Rotorua and Ngongotaha stations attended and the fire was "well involved" when they arrived.
A nearby resident, who did not want to be named, said he raced over to try to help.
"I was seeing if I could help put it out in the bedroom but it spread too fast. I feel sorry for them, they've lost quite of bit of things," he said.
Mr Bootten credited the family for being prepared and having working smoke alarms installed.
"That is so positive to see because, so many occasions, we go along where smoke alarms aren't working and people are injured, they're not getting out as they should do and they're getting smoke inhalation," Mr Bootten said.
"This is a really good example of the whole family remembering what they have learned, it makes the fire service proud to know that we're getting our message across to our children to protect them. It's a big part of our 2020 vision to continue with our Get Firewise [school programme]."
