I know this looks like a very simple and even dumb question, as it would be very easy to check the bands in the website, but it looks that there is something wrong in the specs:

In this website, Apple says that the A1522 model doesn't work on New Zealand:

On this website, Apple says that the supported bands of the model are "1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29". In the Wikipedia page (and other ones), is said that the LTE bands used in New Zealand are 3, 7, 28, which are in the list.

Does someone have a clue of why in the first website Apple doesn't includes New Zealand as a supported country for A1522?
