So, for those interested. Here are some resources and recommendations I found re: heli skiing in New Zealand.
Heli Ski Providers
I've only included those I've personally used/can vouch for. Can update this with more in the future if anyone has personal suggestions of their own!
Loved my time with Southern Lakes. Were professional, friendly, and managed to pick out a package that was perfect for my - then relatively non-existent - ski skillz. Have been back a few times since and am planning to return next season. Great stuff.

General New Zealand Ski Information
General tourism resources for the region. Sure, you're going to be Heli Skiing, but you'll need a place to stay, eat, and other sights to see in the meantime!
As mentioned, happy to add any suggestions to this list. Will likely build this out more in the future. Hopefully this proves useful!
