A large tree with a treehouse which caught fire took about three hours to extinguish.
A Fire and Emergency Services New Zealand spokeswoman said they were alerted to the fire, on Pheasant Ln in Te Puna, about 5.37pm yesterday.
Two fire appliances and two water tankers were sent to the scene.
This morning, a Fire and Emergency New Zealand spokesman said the fire was extinguished by about 8.30pm.
There were no threats to neighbouring houses, but services could not access a water hydrant there and had to transfer water to the remote site.
