Dasler Biv, formerly know as Cullers Biv, was built in 1966 by the NZFS to accommodate wild animal control hunters. Recently painted in red by NZ Alpine Club volunteers. Edit Hut
The Dasler Biv location seems shown correctly on the LINZ map (1120 m), not another 100 m climb up the hill to 1220 m where it would be well above the treeline and across a major gully. A sign on the door says 1200 m! Can't see the hut in the aerial photo but the forest edge is obvious.
