Hollywierd has its own problems with unions. SAG isn't just for actors -- it includes all the tech guys, grips, lighting, FX, caterers, etc. Production has gotten so expensive in the US that it's become too expensive for SF shows -- especially ones with a lot of FX -- to be made here.
New Zealand has more going for it than just gorgeous mountains and countryside; it's cheaper to film there.
