Firefighters will remain through Sunday night monitoring possible flare-ups from a massive fire in Auckland.
The blaze at the old Southdown Freezing Works on Hugo Johnston Drive in Penrose began at about 6pm on Saturday and at its peak 22 fire trucks and 80 crew were in attendance.
The building, about 180 by 50 metres, was fully engulfed and plumes of black and green smoke could be seen several kilometres away.
The property manager of the site believes more than 100 people will lose their jobs as the 20 small businesses which use half the site are closed.
The blaze is not expected to be completely out until Tuesday.
Asbestos risk
Auckland health officials say they need rain and no change in the wind direction to minimise the risk from asbestos from the fire.
The Auckland Regional Public Health Service say it's checking the area for toxic particles.
Its medical officer Craig Thornley says people should keep away from the area, and nearby residents should have their doors and windows closed.
He says if people do feel as though they are suffering adverse affects they should see their doctor.
Criticism Fire Service too slow
Business owners are criticising the Fire Service for not acting sooner to put out the blaze.
The ground, second, third and fourth stories of the derelict building were engulfed in the blaze.
Graeme Torckler, who runs a computer recycling business in the old freezing works site, said the fire brigade did not have its hoses on for a long time after arriving at the scene.
"The fire brigade just sat back and said no we will let this one burn because we don't want this building," he said.
"For a long time they didn't even have hoses on, flames were roaring out - the trucks were up there and the hoses were not even pumping water."
About half a dozen other business owners shared Mr Torckler's opinion.
However, Chief Fire Officer Brian Edwards said the Fire Service was on the scene four minutes after the call was received.
"For someone observing it from outside it would not be too much to see in those initial stages but certainly the fire service did not just arrive and not do anything."
"Processes were being set up to bring in water supplies to feed those aerials as they require a large amount of water to feed them," he said.
