New Zealand has always had an ATPL flight test. The flight test had to be on an approved high performance or complex type. The DC3, Cessna 421 and Piper Mojave were the only piston approved machines at one stage but believe they are no longer. (could be wrong about the Mojave but they now have a King Air)
The NZCAA certifies a small number of Flight Examiners at each airline to conduct the Flight Test on the CAA's behalf. The Examiner certification is only valid for two years and is limited to the Airlines aircraft types but can do external candidates. The Examiner requires a CAA flight check to renew the approval.
I know that Air NZ jet fleet will roster a Flight Examiner and a second pilot to complete an ATPL flight test as soon as the candidate has the required experience and has at least one year on type. The candidate is rostered one training simulator detail and the flight test the following day. The cost of the test (simulator, examiner and crew member) is covered by the airline. The candidate is responsible for the application licence fees.
