Air New Zealand Air Points - Flight departing and arriving Auckland, NZ2961

http://users.pop.umn.edu/~eroberts/nz2961.png

A strange flight on the Auckland arrivals page yesterday. NZ2961 arriving into Auckland Domestic, from Auckland. Shows up on schedule at 17:05 for today. Anyone know what this flight is?

May be a testing flight? (Either real, following maintenance, or virtual for testing the website/departure info feed.)

There are some on today's schedule too.

Generally around that 5-5.15pm time slot

There has been in b1900D doing touch and goes heaps lately
