I've been doing some experimenting around Marlborough, but representing NZ is kind of tricky, that's for sure. The main problem I have is pinus radiata, which is not represented at all, and other common but under-represented trees like macrocarpa.
There are other choices to represent pine forests, as long as you don't get too close. There are various sizes of pine scrub, which are handy -- they can represent macrocarpa at a pinch -- but these are not as neat as pine trees.
At the moment, because its Autumn, my concern is to keep the riotous colour to a minimum:) There's a bit of colour around cities, of course, but generally out of town New Zealand stays pretty green. Excluding poplars, of course, which are really nice to put around the rivers etc.
For NZ bush, it is even trickier. For low dense bush (like around Marlborough Sounds) I may just leave the photo un-autogenned, just putting a few 'pines' in to give it a bit of height.
A good choice for real big NZ bush is Tropical Rainforest. Here's a shot of my test spot which I use to try different classes -- in Picton harbour.
This is autumn, you can just see a tiny bit of colour, but for the rest of the year its a nice even green.
