Seven fire trucks are attending a blaze at a Grey Lynn home with black smoke pouring out the sides.
Emergency services were called to the fire on Beaconsfield St at about 2.30pm today.
A fire service spokeswoman said there have been no reports of anyone involved and luckily no injures.
"All I know is that it was well ablaze when they got there but I understand it is cooling down."
A fire investigator is attending the scene.
The spokeswoman said she was unaware of the damage and it was too early to say how it started.
