I've decided on a 1980 cut-off date for former exotic species. It's much easier.
However, this is an interesting item I found when looking through old newspaper articles - Wellington Zoo had Tooth-billed Pigeon in 1916:
Papers Past | Newspapers | Evening Post | 18 December 1916 | This page
The article says:
Here, too, is the strange tooth-billed pigeon, most interesting to ornithologists as the supposed nearest relative of the dodo. To New Zealanders who have not studied bird history this peculiar bird is notable chiefly as a souvenir of the occupation of Samoa.
Some further searching shows that it was at the zoo from December 1914 to sometime close to April 1919, meaning it lived there for around four and a half years.
The Zoo Notes article in this newspaper from 22 December 1914 (
Papers Past | Newspapers | Dominion | 22 December 1914 | This page) talks about the bird's arrival from Samoa, along with "a handsome pair of other Samoan pigeons (I presume Carpophaga pacifica, or oceanica), and a rail, also from Samoa"
The shipment had just recently arrived, and the birds would be going on display that week. Further down the article it continues:
...
His Excellency the Governor received from our Expeditionary Force that recently took possession of the Samoan Islands, and on the advice of His Majesty's Ministers for New Zealand, presented to the Zoo. The valuable present comprised one tooth-billed pigeon, a very interesting bird; two pigeons of a species that has acquired powers for eating fruit, a species very interesting to ornithologists, and of striking appearance to every lover of pigeons; one pretty little dove, one interesting little rail, and two Java sparrows.
(Other articles call the dove a Diamond Dove, which is a bit odd. The rail wasn't specifically named but may have been a Banded Rail which are common in Samoa).
The behaviour of the Tooth-billed Pigeon at the zoo is discussed at length in a newspaper article for February 2015 here:

The Zoo Notes for 28 April 1919 notes, at the start of a long list of deaths, that the Tooth-billed Pigeon had "recently" died.
