"The number of takahē breeding pairs shows a good gender and age balance in the population and is critical to being able to keep pushing takahē further away from extinction."

About two-thirds of the takahē population is spread across 18 secure island and mainland sanctuaries.
In 2018, takahē were released into the Heaphy Track area in Kahurangi National Park in an to attempt to establish a second wild population outside of the Murchison Mountains.

"This was a major step towards the long-term goal of securing self-sustaining populations in areas of their former natural range," Ms Sage said.
"The Kahurangi population has grown and now has 31 birds. Almost all of the takahē have been gaining weight since their release. It is planned to release another 10 takahē there early next year."
