Dylan Matthews at Vox argues NZ has the best designed Government in the world. He cites three things which are crucial:
- NZ’s MMP system which delivers proportional results but also retains electorate seats
- NZ’s Unicameral Parliament with no Upper House. He argues Upper Houses tend to be useless and undemocratic.
- NZ’s Constitutional Monarchy which provides a Head of State with no legitimacy to interfere in domestic politics
I’d don’t agree with all his arguments but he makes a good case. I’d add a 4th. No state parliaments. No disputes over what is the role of central government and state governments, and no duplication of multiple police forces, education ministries etc.
