A baby has been injured in a large house fire in West Auckland this morning.

Fire, police and ambulance arrived at the scene of the Fruitvale Rd property in New Lynn which was engulfed in fire.

Fire Service northern shift manager Karen Larking said everyone got out of the burning home but a baby was treated for smoke inhalation.

Everyone was safely outside the home when emergency services arrived.

The alarm was raised at 6.34am.

A photographer at the scene said enormous plumes of smoke covered the area with curious residents coming out of homes and on to the street in nightwear with children in tow to see what was happening.

The fire was still burning fiercely an hour after it started.

He said as well as a large number of firefighters at the scene the street was filled with a big police presence including dog handlers.

Two men and one woman, believed to be the occupants, went through a decontamination wash along with firefighters who had entered the burning home.

The wash is typically used for those who have been in contact with potentially dangerous, contaminated substances.

He said the home's occupants were stripped of their belongings and made to wear boiler suits. The men were both in day wear but the woman was still in a dressing gown.

Firefighters also changed into boiler suits and their gear was taken away for treatment.

This afternoon police confirmed there was not a clandestine lab in the house.

Fire investigators were now determining the cause of the blaze.
