"Once inside the house the police officer searched through the black smoke but was unable to locate the occupant due to how dark and thick the smoke had become.
"The police officer was struggling to breathe and was forced to go back to the window to get air. He then made a second attempt crawling through the house feeling his way along the floor trying to find the occupant.
"He ran his hand across the floor and located the female occupant and pulled her to the window."
The officer was unable to lift the woman out of the window, but was able to get the woman out of the house when a second officer arrived.
Fire and ambulance staff arrived on scene a short time later and ambulance took the 77-year-old woman to Tauranga hospital for treatment for smoke inhalation.
A 54-year-old man at the scene has also been taken to hospital.
The police officer was also taken to hospital due to cuts on his hands and for observation due to inhaling smoke.
"The quick heroic action of the Police officer tonight was able to prevent a tragedy from taking place," the statement said.
"The elderly female is stable currently in Tauranga hospital with her family at her side."
The fire has now been extinguished.
