Boxes carrying very precious cargo were delivered to Maungatautari mountain on Tuesday afternoon.
Thee rare and endangered Takahe had travelled all the way from Kapati and Burwood to make their new home in the sanctuary.
Only about 260 Takahe remain in the world, with only about 75 breeding pairs.
A pair were released on the main mountain and a female was released into the southern enclosure.
Waikato Times photographer Mark Taylor was there to capture the birds' release.
