Etymology

The Māori language word kiwi is generally accepted to be "of imitative origin" from the call. However, some linguists derive the word from Proto-Nuclear Polynesian * kiwi, which refers to Numenius tahitiensis, the bristle-thighed curlew, a migratory bird that winters in the tropical Pacific islands. With its long decurved bill and brown body, the curlew resembles the kiwi. So when the first Polynesian settlers arrived, they may have applied the word kiwi to the newfound bird. The bird's name is spelled with a lower-case k and, being a word of Māori origin, normally stays as kiwi when pluralised.

The genus name Apteryx is derived from Ancient Greek 'without wing': a- (ἀ-), 'without' or 'not'; ptéryx (πτέρυξ), 'wing'.
