I used Origin recently (i.e. yesterday) between Nelson and Auckland. To be honest the load factor was about the same as Air NZ when I have previously flown the route. 19 people on a J41. Flying down there a couple of weeks ago (also from Auckland on Origin) from memory it was 13 of us on board.
ZK-JSA was parked on the grass at Nelson - looked to be out of service.
I hope Origin Pacific survive - they make a nice change from Air NZ.
Cheers,
