You'll find that all of NZ's 320s are owned by Freedom Air, or what is now known as Zeal 320, also the holder of the Air Operators Certificate. The company was set up in the latter stages of Freedom ops and many may have noticed that at this time, any International Flights using A320 equipment changed their flights numbers to begin with a "7" instead of a "1". e.g. AKL SYD NZ101 became NZ701 but reverts back to NZ101 if B767 or B777 equipment are used.
Bit of trivia for the Buffs.
This particular craft is ZK-OJL and has been on lease to Star XL/XL Airways in Germany, hence the German rego and was due to be returned to Zeal 320. Interesting that Airfleets.net already have the Aircraft listed as wriitten off. They don't muck around.

Sad about the demise of the frame but especially for any lives that are lost.
