The Department of Conservation has cancelled balloted tahr hunting opportunities for recreational hunters in Wilderness areas and Westland Tai Poutini National Park this summer.
Its planned tahr cull is still on hold while it reviews operational procedures in the wake of last month's helicopter crash at Wanaka.
DOC had planned to allow air access to the Hooker/Landsborough Wilderness Area, Adams Wilderness area and nine sites in Westland Tai Poutini National Park in January.
Lead operations director for tahr control, Andy Roberts, said feedback from some members of the Tahr Liaison Group suggested January was not the best time for the balloted hunting.
"Feedback suggested hunters would prefer not to undertake tahr control during this time as kids wouldn't have weaned from their mothers. We also heard from helicopter operators who won't have capacity to carry hunters due to increased tourism demand for flights."
