What is this ?

First noted at Rangiora in about July 2004 is this unknown helicopter type.

Air-96 is on the panel below the engine.
Reputed to have done about 1000 hours cattle mustering in Australia.
From what I observed it did not seem to have the grunt to lift off its trolley on a cool Rangiora day - let alone from a hot Aussie outback paddock !.
Engine on arrival was a Rotax 618 of around 70hp and a Rabe exhaust.
I believe it has been re-engined since but appears to have gone off the scene.

Anybody any clues as to what it is ?
