I was reading about tort reform once and stumbled upon NZ's ACC concept and was staggered by its effectiveness. I suspect its success is due in part to NZ's population size, but any system that ensures all accident related issues are covered AND for the most part renders the civil courts redundant for personal injury claims is pretty phenomenal. I don't have a source for this, but I also remember reading that the ACC is now one of NZ's largest institutional investors with something like $30bn under management!
