A type rating in NZ on a 206/182 or any similar single is pretty straightforward. As long as you can drive a Cessna you shouldnt have too much trouble getting the rating. You only have to do 1 hour.
If you were looking to do flying in Aussie, as Tailwheel says, they dont have individual a/c ratings here, Its single engine, Constant speed, tail dragger, and retrac endorsements and you're away laughing.
