Thanks lads, turned out to be a bit of a pain doin the fern detailing wrapping under the tail, but got there in the end.
File has been uploaded to avsim tonight, give it a day or so then search for "Air New Zealand B1900D" or similar, should turn up. If you notice anything weird drop me a line and I'll patch it. I ended up painting it with the alpha layer on to give it a little reflection as in the real-world machine (based on photos I've seen) and have included a set of alternatives with no alpha should you prefer them. Here's the finished product...
