Maps from Tahr Control Operational Plan: 2022–2023

Maps are posted to this page following tahr control operations. These maps show where operations have taken place and how many tahr have been controlled.

As DOC has not targeted identifiable male tahr outside of the national parks (Management Unit 4), observations of identifiable males across parts of 425,000 ha of public conservation land have been recorded and shared on this page to help hunters plan their next hunt.

DOC aerial control within Management Units 3 (Gammack/Two Thumb), 4A (Aoraki/Mt Cook national park) and 5 (Ben Ohau) are complete under the 2022/23 Tahr Control Operational Plan, which runs through to 30 June 2022. No operations are planned for Management Unit 7 (Wills/Makarora/Hunter) under the 2022/23 plan.


  • DOC is only targeting all tahr inside Aoraki/Mount Cook and Westland Tai Poutini National Parks (Management Unit 4), and outside the feral range. This will help DOC to meet its legal obligations and protect these special places.
  • Outside of the national parks (Management Unit 4), identifiable male tahr have been left for hunters across 425,000 ha of public conservation land.

MU 3 Gammack – Two Thumb July/August 2022 Summary sightings map (PDF, 2,053K) 170

  • Sightings of identifiable males observed in management units outside of Management Unit 4 (Aoraki/Mount Cook and Westland Tai Poutini National Parks) have been mapped.
  • The circles represent the size of the tahr groups observed.
  • It is possible some of the recorded sightings may be of the same animal observed on different occasions.
  • If sightings are not recorded on a map at a particular location, tahr may still be present. DOC has not flown or hunted every valley within an individual management unit, or all management units in 2022/23.

  • The circles represent the size of the tahr groups controlled/observed. In some cases individual animals belonging to clusters have been removed.
  • Some areas may have been flown more than once.

Maps from tahr surveys in the South Rakaia/Rangitata and Gammack/Two Thumb Management Units (1 and 3)

DOC is publishing maps showing areas where large groups of tahr have been observed in popular hunting areas.

These observations were recorded over late Summer and Autumn 2021 as part of tahr population surveys in the South Rakaia/Rangitata and Gammack Two Thumb management units, east of the Southern Alps.

These maps are being published to encourage hunters to contribute to tahr control. More maps will be published when data is available.


  • The surveys were undertaken between late February and early May 2021.
  • The areas were mapped based on surveys undertaken on three separate occasions, and high tahr densities were observed each time.
  • Other areas not surveyed within the two management units may also have high densities of tahr.
