The MMP system is the voting system that we are currently using in New Zealand. This system allows each voter to have 2 votes. The first vote is for the political party the voter chooses. This is called the party vote and it decides the total number of seats each political party gets in Parliament. The second vote is to choose the MP the voter wants to represent the electorate they live in. This is called the electorate vote. The candidate who gets the most votes wins. They do not have to get more than half the votes. What other countries has MMP been used in? MMP has been used is Germany for more than sixty years. What are some other names for MMP? MMP is sometimes known as AMS in the United Kingdom, AMS stands for Additional Member System. Parties are allowed to have something called a coalition, a coalition is a temporarily alliance. So all votes each party gets will add up and be the same votes for them as a group.
