New Zealand goose
genus of birds
The extinct New Zealand geese are a genus, Cnemiornis, of very large flightless geese in the family Anatidae. The genus, endemic to New Zealand, consists of two species: the North Island goose (Cnemiornis gracilis) and the South Island goose (Cnemiornis calcitrans).
Description
This goose was as large as some small moa. The North Island species had 15 kg (33 lb) in body mass while the South Island species reached 18 kg (40 lb), far surpassing Canada and Cape barren geese. They were flightless, with much-reduced webbing on the feet, an adaptation for terrestrial dwelling similar to that of the nene of Hawaii. They are usually considered most closely related to the Cape Barren goose of Australia.
Extinction
They were never particularly common, and like many other large New Zealand endemic species they were subject to hunting pressures from the settling Polynesians, as well as predation upon their eggs and hatchlings by kiore, or the Polynesian rat (which accompanied the settlers) and the settlers' dogs, and were extinct before the arrival of European settlers. The Māori name of the North Island goose (C. gracilis) was "tarepo".

Begin with the source’s own compact description: “New Zealand goose” is genus of birds. The dossier treats that line as a proposition to test through Zealand, goose and genus, not as a finished interpretation.
Why this record matters
The phrase “genus of birds” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 8, 2025. The linked authority identifier is Q3443727. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
