Batman:

It just does.

That's the crazy MMP system. Even without the Maori seats,nobody knows what happens until the votes are in, the formula is more complicated than rocket science.

Im not sure if your joking or not.

Its not complex. If you get party votes, you get that % as seats. As long as you get one seat, or you get over 5% of all party votes.

If you get seats and 51%, you get 51% of the seats.

If you get one seat, and 4.5% of the votes , you get 4.5% of the seats

If you get no seats, but get 7.8% of the party votes, you get 7.8% of the seats.

Thats pretty much it.
