Firefighters battling fires at two large sheds just outside Pukekohe, south of Auckland, have got the blazes under control.
The fires were noticed at a property in Ostrich Farm Rd around 5.30am.
Fire Service shift manager Daniel Nicholson said four fire trucks were there, with two water tankers.
The fires had been contained but firefighters were still working to put them out, he said.
He said the sheds were 50 by 20 metres in size and were well ablaze when firefighters arrived.
Nicholson said it was too early to say what caused the fires.
