dictatorship in new zealand

Part two- how it will happen here

Germany was democracy before it was dictatorship. It become a dictatorship gained enough votes to become government on it's own and passed a law banning all other parties.
New Zealand is a democracy. If a parties gain over 50% percent of the vote they can form government by themselves. This was also how it was in Germany. A governing party could then pass a law making New Zealand a dictatorship.
So there is a possibly be a democracy here.
