Don't copy New Zealand MMP: half of our members of parliament are chosen by the parties (list vote) and have no voter constituency. It is shitty. The 5% parties get far too much power e.g. Winston Peters (and I read about coalitions causing problems in Germany). And the 10% parties often refuse to do anything because they refuse to cross the floor (e.g. the greens never work with our conservatives so their power is wasted - they only exercise their power when the majority party is lefty and enough greeny).
