Poliltical compass points me nowhere

Liberation suggests people who are undecided about who to vote for tomorrow try the political compass.

I did and got this result:

Economic left/right 3:88; social libertarian/authoritarian -2.87 is slightly  more centrist and libertarian than last time I did the test when I was right  4.38, Libertarian: -1.74.

But it’s absolutely useless as a guide for voting because there are no  New Zealand parties in that square:

I’m taking that as an indication of faults in the test and analysis of the parties rather than my decision and sticking with two ticks for National.
