Qantas B737-838 at Wellington

Spotted at Wellington on Sunday afternoon was this Qantas B737-800 series aircraft with the Australian registration of VH-VXL. What attracted me to this particular aircraft was that the landing lights were flashing/alternating as it came in - quite different from most other aircraft that frequent Wellington.

Although not confirmed, I understand that this aircraft may have been filling in for Jetconnect [branded as Qantas in New Zealand] on some domestic sectors recently.
