The Fire Service is investigating a fire at an abandoned house inside the Christchurch red zone today.
Emergency services received multiple 111 calls about a house fire on Avonside Drive about 6.50am, said Fire Service spokesman Tim Reynolds.
"We responded three fire service appliances and a tanker, and when the fire service arrived the house was well involved."
Reynolds said it was too early to say whether the fire was deliberately lit.
He said fire did not spread to neighbouring homes.
