Lester, while New Zealand may have been used as the name of the country after European discovery, Māori did not have the concept of one name for the whole country. The name New Zealand could be considered imposed on Māori by tauiwi (non-Māori) from 1642, more so after 1769 and at least with some legal standing from 1840. I will accept that Aotearoa was probably not used by Māori until about 1860. However, modern Māori seem reasonably comfortable with that usage. Few profiles use Aotearoa on WikiTree. I have seen some with Nouvelle Zelande as well on the profiles of French speakers. The use of Aotearoa is an attempt, at least, to honour the Treaty, and I am sure in time will become the official name in all spheres.
