RFI: "Status" of birds on Tiritiri Matangi Island New Zealand

Hello:

I will be visiting New Zealand in October and my hosts are planning to
take me to Tiritiri Matangi Island. Sounds like it will be a great
experience, but I am wondering if anyone can comment on the "countability"
for bird listing. Apparently, native vegetation was established on the
island between 1984 and 1994, and "a number of species of threatened and
endangered birds have been successfully introduced"
http://www.tiritirimatangi.org.nz/

But to me, "introduced" birds are not "countable" until they are fully
"established". I would appreciate any comments on the specific situation
of Tiritiri Matangi Island.

Thanks,
David
