Saw that earlier but didn't get back to capture it. There are about 3 aircraft doing that sort of stuff around NZ. All of the NZAA area was done at low level about a week ago lots of circles at the end of some runs to let aircraft arrive and depart.
It's been going for the past couple of days in the most inconvenient places, especially when we're trying to land and they're doing runs overhead Ruapuna
