I arrived at the Aero Club on a warm and not-too-windy day just in time to New Zealand's on Mitsubishi MU-2B-30, ZK-KOH, depart for Wellington.
This aircraft is operated by Search and Rescue Services of a Taupo address and so I presume it was operating as an air ambulance.
In other, semi-related news, the local Life Flight rescue and air ambulance service has their open day tomorrow, Sunday 22 March. Present will be the fixed wing and helicopter aircraft, other emergency services, food and drink and plenty to do for the kids. Even if the weather is a bit dodgy, they have a couple of big hangers and you'll be able to look inside their aircraft.

Do take a look and support them if you are able. They are located next to the Aero Club, so are very easy to find!
