"The pond is surrounded by lots of little retreats. The takahe will like that when there are noisy school groups around," Mr Smith said.
Watched by Orokonui Ecosanctuary staff, Paku the female takahe takes her first steps into the open yesterday.
"The whole idea is for people to come and see them so, hopefully, the feeding bay will keep them around. Now, they just have to get used to people."
Otago Natural History Trust chairman Neville Peat said only 200 takahe were believed to survive in the New Zealand wild.
"There were about 300, but they suffer from low birth-rate and predation. The largest population is in the Murchison Mountains in Fiordland, where there are about 80.
"The other pair were invisible because they were fighting with each other. Quammen went down to the bottom gate and Te Hoiere stayed up the top."
The new pair were unlikely to breed, Mr Peat said.
"We've always thought we could breed takahe here, if we had a breeding pair. But, these two have got fertility issues, with inbreeding. They look like they're getting on really well, though.
"We hope they will raise awareness of the plight of the takahe."
