A fire has extensively damaged part of the Auckland Film Studio complex overnight.
Auckland Council, which owns the property, said this morning Studio 3, one of five film studios on the site, was not being used for filming and the damage was not expected to affect filming operations.
The council said the building was insured.
More than 60 firefighters battled the blaze at the Henderson Valley Rd complex for more than three hours before they got it under control.
In that time the 50 metre by 100m building was badly damaged and the Fire Service said it would probably need to be demolished.
The Fire Service was alerted by an automatic fire alarm at just before midnight, Assistant Area Commander John Booth said.
Firefighters with 18 fire engines from around West Auckland and as far away as Ellerslie fought the fire at its peak, he said.
Booth said no injuries had been reported. He could not comment on whether the fire was considered suspicious.
Fire investigators have been at the complex this morning to find the cause, and four fire engines would stay at the studios for part of this morning to keep an eye on the area.
The Auckland film studios is one of the largest complexes in the country, used for both international and domestic projects.
Productions like Mr Pip, Legend of the Seeker, and Power Rangers Ninja Storm have been based at the studios.
Despite the fire it seemed to be largely business as usual for the film studio's crew this morning. Staff arriving for work shortly after 7.30am were directed through the gates for their crew call.
Earlier reports the building was being used for filming of Crouching Tiger, Hidden Dragon II – the Green Destiny, were not correct, the council said.
