The 18-month-old toddler injured when his Mount Wellington home went up in flames on Saturday remains in a critical condition in Middlemore Hospital.
Emergency services were called to the house in Malone Rd, which was well ablaze, just after 8am.
Fire service area commander Mike Shaw said a little boy was given CPR and revived at the scene before being taken to hospital.
The cause of the fire was still under investigation.
