Your Feature Request / Idea
I've already posted something similar on the subreddit, but the gist is that there aren't any named dinosaurs, so if we stick to dinosaurs permanently, then New Zealand would loose out.
There is one major site for dinosaurs in New Zealand, the Maungitaniwha member of the Tahora Formation, also known as the Mangahouanga Stream, and it does have some material that could be used as flimsy grounds to extend the range of some named dinosaurs from the Latest Cretaceous (Campanian-Maastrichtian) of Antarctica or South America.
The strongest candidate is a probable Nodosaurid, which could used to put Antarctopelta in New Zealand.
There is a small ornithopod, originally classed as a Dryosaurid, that could be used to extend the range of Trinisaura or Morrosaurus.
Also there is a tail vertebra from a Titanosaur that could be used to extend the range of a small, similarly aged Titanosaur, such as Saltasaurus.
This would be embracing inaccuracy, though arguably to a positive effect and could potentially host the mentioned Antarctic dinosaurs if changing the map is not a viable option.

A New Zealand titanosaur tail vertebra, with some details on the site itself.
