The first two images are of a Kawasaki BK117 B2, ZK-IBK, registered to Skyline Aviation Ltd of a Napier address and used as a rescue helicopter/ air ambulance.
The next three are of a CTC Diamond DA42 Twinstar [also known as the "Death Star" in some circles...], ZK-CTM. This is pictured tied up for the evening and included my first opportunity to photograph the cockpit of one of these aircraft. The final picture is of an Aerospatiale AS350 BA, ZK-HZN, registered to Search and Rescue Services Ltd of a Taupo address. This is also used as a rescue helicopter/ air ambulance.
Enjoy the pictures!
