Referendum NZ 2011, Different voting systems

* FFP
+ Only one vote for the local MP and that mp will represent in the parliament.
+ Hard for small party to win seats.
* PV (Preferential Voting)
+ Like FFP but you rank your local MP instead. Ranking from 1 to 4
* SM (Supplementary Member)
+ Like MMP but smaller party will have less seats than the votes they get.
* STV (Single Transferable Vote)
+ Each electorate has more than one MP
+ Easy for small party to get elected.
