There is this website I found via facebook, which you can take a test and work out where you are on the political septum. While its not an exact since, its not to bad over all. If you want to see where I am, you will need to visit my facebook profile.
It also has where particular politicians and parities are in some counties, including New Zealand. It's striking how right wing New Zealand, the US and the Uk all are. Fi will probably disagree with where United Future is,
