Most people seem to give the same reason to me in conversations as to why they support the MMP voting system – Mixed Member Proportional representation.
The reason is profoundly democratic: their party vote always counts no matter where they live in the country or how safe or how marginal the local electorate might be.

Under first past the post, it didn’t matter who you voted for if you lived in a safe electorate because the local MP of whatever political party would always be elected.
What is underplayed in these conversations is how close all elections are in New Zealand, and how likely it is that your vote might be decisive rather than just one of millions.
Under MMP, the last seat in Parliament is a contest between several parties. If anyone just gets a couple of dozen more votes, they get another seat.
In the current parliament of 121, the National Party Government has 59 seats, with the ACT party one seat and the United Future Party one seat.
One more seat for ACT or one less seat for the National Party would have made a big difference to the election outcome. ACT was only 45 votes short of getting that second seat in the 2011 General Election.
Note: Under MMP, the New Zealand House of Representatives is a mix of MPs from single-member electorates
and those elected from a party list, and a Parliament in which a party’s share of the seats roughly mirrors its share of the overall nationwide party vote. There is a minimum party vote threshold to get into Parliament. The party votes of those parties with less than 5% of the party vote do not count unless they win a constituency seat.
Many people readily concede many of our regulations are insane, badly designed, and harmful.

What do political parties do?

The purpose of political parties is to popularise ideas and then present a slate of pre-screened candidates committed to delivering on these ideas, to controlling each other to ensure they stay staunch, and have a defined and published world-view or ideology on what they will do when various contingencies arise. A market for assurances arises through political brand-name capital.
A conviction politician is one who has invested is so much brand-name capital that they know they are finished if they change their views. People vote for them because they know what they will get. When the brand is betrayed, voters punish this unfaithfulness severely – execute one, educate a thousand.
Schumpeter disputed that democracy was a process by which the electorate identified the common good, and that politicians carried this out:
• The people’s ignorance and superficiality meant that they were manipulated by politicians who set the agenda.
• Democracy is the mechanism for competition between leaders.
• Although periodic votes legitimise governments and keep them accountable, the policy program is very much seen as their own and not that of the people, and the participatory role for individuals is usually severely limited.
Modern democracy is government subject to electoral checks. Citizens do have sufficient knowledge and sophistication to vote out leaders who are performing poorly or contrary to their wishes.
The power of the electorate to turn elected officials out of office at the next election gives elected officials an incentive to adopt policies that do not outrage public opinion and administer the policies with some minimum honesty and competence.
Political parties, by investing in brand names and ideologies governments have betrayed their promises make it easier to vote out governments have betrayed their promises

The Hockey Stick of Human Prosperity

On a timeline of human history, the standard of living resembles a hockey stick – flatlining and then skyrocketing in just the last few centuries.
Specialization and trade explains the astonishing growth of productivity and output in such a short amount of time—after millennia of famine, low life expectancy, and incurable disease
