This subject has been previously discussed in the community, but seeing the update on the fur of the feral goats, I think it would be minimally viable for them to add the himalayan tahr to Te Awaroa, after all, there is even their icon in the game, and this species is one of the best know in NZ.
I think it would be interesting if they made it as a more difficult species to hunt, living entirely on the top of the two mountains of the reserve, unlike chamois, which occasionally descend to the foothills to feed. A hunting style similar to the alpine ibex on Classic would be perfect for them.
