Hunter, who has been an advocate for conservation projects around the world, was made the FLR Trust's patron at the release.
Takamoana was hatched as part of the BNZ Save the Kiwi Trust's Operation Nest Egg, which involves incubating eggs taken from the wild.
Once the hatched kiwi are large enough to defend themselves against stoats, they are released back into the wild.
BNZ Save the Kiwi Trust executive director Michelle Impey said rearing and releasing 100 kiwi would usually take twice as long.
"The FLR Trust team have got it down to a fine art and it's wonderful that some of the chicks released three or four years ago are now breeding themselves - further adding to the population."
Half the 100 kiwi hatched so far have been released at Maungataniwha, where the eggs came from, and the other 50 were relocated to the Cape Kidnappers and Ocean Beach Preserve.
Conservation Minister Kate Wilkinson today applauded the trust's private kiwi breeding project for its important contribution to conservation since 2006.
She also paid tribute to Mr Hall, who she said was a driving force behind the project.
"I am very impressed by what Simon and his team have achieved. It is important these initiatives are encouraged," Ms Wilkinson said.
"Not only are the trust restoring kiwi, they are working to control pests and bring back other threatened plants and animals at sites as far as Fiordland.
"Their work demonstrates the co-operation that is developing all over the country between private land owners, the business sector, like-minded restoration groups and the Department of Conservation (DOC)."
DOC regional conservator Alan McKenzie said privately-funded conservation and regeneration projects were "without doubt" the way of the future.
The department could maintain the status quo, but a step-change in the re-establishment of native species would require significant investment that the private sector could deliver.
"We see our role as facilitating this, and working with organisations such as the FLR Trust to establish the framework for a national model."
The kiwi Takamoana was named after Karaitiana Takamoana, an important local chief in the 1800s who was also Mr Hall's great-great-grandfather.
