"I yelled at her, 'I know you want to keep your valuables but your life is more important'.
"She was stressed because she didn't know what to do and panicked because of her valuables but I managed to get her out about three minutes before the house started falling apart," Duran said.
Fortunately, no one else was inside the house at the time.
"It went down really fast, she was lucky to be out when she was," Duran said.
He managed to get footage of the blaze as fire crews fought to put it out.
Emergency services arrived at the burning property at 6.50am.
Papatoetoe Fire Station's senior station officer Tony Searle said when their three fire crews arrived the woman was clutching a bunch of photos watching her burning home.
"She was lucky to get out nice and early but unfortunately it was a bit late for her house to be saved," Searle said.
Searle said it took three hours to completely extinguished the blaze and the house was now "unlivable."
Housing New Zealand are now looking after her, Searle said.
"There is some suspicion of arson and it is possible but nothing's been ruled out yet and police are dealing with that," Searle said.
Duran said he gave his contact details to police and left shortly after.
"I'm not sure if [the woman] was hospitalised or not."
Police say they are treating the incident as a suspected arson and are in the process of examining the blaze. Inquiries are continuing.
