Fatal Northland blaze 'likely sparked by TV'

The Kaitaia man who died in a house fire on Thursday was Hugh David Aarons.
The 51-year-old was awake when the fire started shortly before 7.30am and is thought to have tried to flee the burning unit.
Neighbour Bob Lloyd, who lives on the other side of Summerville Ave, heard Mr Aarons' calls as he kicked in the doors in a desperate rescue attempt, but was beaten back by intense heat and smoke.
Fire safety investigator Craig Bain, who spent much of Thursday scouring the unit for clues, said the fire had started in a corner of the lounge.
The most likely cause was electrical, probably in the TV.
Mr Aarons was partly disabled as the result of a brain haemorrhage and suffered from medical conditions, including epilepsy and asthma, but it is not clear if those played a part in his death.
Known to most as "Hughie", he lived alone but had many friends in the town.
He was a regular at Chances bar and the Kaitaia RSA, where he was a member of the pool club.
He walked into town daily and was well-liked in the neighbourhood.
Mr Aaron's twin daughters, who turn 25 next month, live in Kaiwaka and Australia.
His former partner, also from Kaiwaka, visited the site of the fire on Thursday, as did many distressed friends.
Smoke alarms were installed in the unit in 2006 under the Fire Service's Te Kotahitanga programme but investigators could find no trace of them.
Mr Bain said if a smoke alarm developed a fault, the first thing to try was cleaning it.
If it was still faulty, the battery needed replacing; if that didn't help, the whole alarm should be replaced.
Smoke alarms were working in the adjoining unit, which was unoccupied at the time of the fire.
The Housing New Zealand units are separated by a fire wall which saved the other flat from serious damage.
