Firefighters are fighting a fire in hills near Helensville, north of Auckland.
Fire and Emergency NZ received multiple calls about 12.40pm on Saturday, saying there was smoke on the hills behind Rautawhiri Park, a spokesman says.
Firefighters found a fire covering about a hectare when they arrived.
A helicopter and nine fire appliances are being used to fight the fire, with another helicopter on stand-by.
The spokesman said he couldn't confirm if the fire was contained yet but there had been no calls for more resources.
"It is a bush fire involving pine trees," he said.
The fire was not threatening property.
