The Takahe recovery programme is doing well and 10 more young birds have been released into the wild, Conservation Minister Maggie Barry says.
She's just helped release them in Fiordland's Murchison Mountains and says they've been trained for more than a year to forage and look after their own chicks.
There are fewer than 300 Takahe left and the endangered species suffered a setback in August when four were mistakenly killed during a Pukeko cull.
"This year has been a very successful one for Takahe recovery with 30 birds set to bolster the wild population in the Murchisons," Ms Barry said.
Burwood Takahe Centre near Te Anau is a crucial part of the recovery programme.
It's home to 22 breeding paris whose offspring are helping restock the population in Murchison, the only place where Takahe are seen in the wild.
