The FB groups:
Main NZAC site:
https://www.facebook.com/groups/5638346254/ There are randoms posting on here, but not many.
Australia Section:
https://www.facebook.com/groups/nzac.australia/ Probably better for finding potential partners, though they'll be travelling from Australia, obviously.
The NZ climbing community is friendly enough, I've found, but I'm Australian and have been going there a while. It's probably not so easy to just rock up and find multiple partners at short notice.
Aoraki/Cook and the other high peaks are pretty serious and often not conducive to climbing with someone you just met down at the village or in a town - or online. Access is physically tougher and more dangerous than in the Alps, if not as technical. Help is non-existent or far away.
You need proper crevasse-rescue and glacier travel skills, practiced together and ideally a partner who is psychologically similar in what risks they will accept, what suffering they will put up with etc, how willing to fail miserably etc, how long they can sit in a hut in the rain, how well they can not freak out downclimbing narrow exposed ridges of choss etc.
