Educated guess based on flight deck gossip would be mid $50's for a new FO at Nelson (Q300) and mid $60's at Mount Cook (ATR), base figures before any allowances.
Honestly, I've been away from the Link group for many years now, as have the guys I speak to but those figures should be in the ballpark.
As for working conditions, I believe the Link Pilots/Unions have been leaning on management to get better TOD pairings, reducing the amount of downtime and consecutive overnights. I gather they've had moderate success.
