"While the South Westland DOC office had the best intentions, we will be cancelling this opportunity based on feedback. The next opportunity for balloted hunting will be in late April next year during the tahr rut.
"The tahr ballot is about authorising aircraft landings on Wilderness areas and the National Park. Keen hunters can undertake recreational hunting on public conservation land anytime during the year.
"We will be continuing to work with the Tahr Liaison Group to identify potential ballot opportunities, where recreational hunters can contribute to tahr control.
"Over the summer months DOC will be focusing on monitoring the size of the tahr population and the damage tahr are causing to precious alpine and sub-alpine vegetation like the Aoraki/Mt Cook lily.
"While our current best estimates put the tahr population on public conservation land at more than 35,000 animals, a third year of population surveys will refine this estimate.
Roberts said DOC's aerial tahr control operation is still on hold following last month's fatal helicopter crash in which Department of Conservation workers Paul Hondelink and Scott Theobold died alongside pilot Nick Wallis.
"There is no confirmed date for DOC's tahr control work to resume but it's unlikely to be before February next year."
DOC said it was committed to working with the hunting sector to reduce the tahr population over time to within the limits of the Himalayan Thar Control Plan 1993.
