The first pairs were released last Friday and a further 20 robins are due to be released in early May.
Sanctuary chairman Peter Jackson said volunteers had worked for more than a decade to prepare habitats for missing wildlife and bring them back into the sanctuary.
Auckland Council's open sanctuary senior ranger Matt Maitland said volunteers had to train the robins to respond to song before catching them.
"They'll then come check out who's in their place. You then can throw sticks in front of them, which mimics the idea of invertebrates falling to the forest floor.
"You can then throw an actual worm to them and they'll pick those up, and so what they do is they get accustomed to coming to the cues that we give them, so that when we do that we can then lure them closer and closer to a trap."
