This property is the old Forest Service Headquarters and camp.
The Forest Service was abolished in 1987 and the environmental and conservation functions were taken over by the newly established Dept of Conservation. The logging operation and associated land was passed in to the NZ Forestry Corporation.
Significant buildings remain and it appears that at least some of the camp is used as rental accommodation.
There is plenty of safe parking but please remember this is a rural highway if you have children with you.
