I believe that Air Gold Coast have a C210 available to them for training. Not sure of the details, it's after my time.
While we're (sort of) on the subject, can I please ask that unless we're Kiwis, in NZ, talking about ZK-registered aircraft, can we please stop referring to it as a type rating/endorsement? In Oz we have one all-encompassing class endorsement: Single-Engine Aircraft <5700kg. Everything from a Jabiru to an AN-2!
