"Voters roundly reject MMP"

My father was telling me about the new referendum one day. He said he was voting against it just because it would complicate things even more. I agreed with him. And as a result, the number of seats that smaller parties (i.e. the NDP, or Green Party) could obtain decreased significantly.

Apparently, the majority of Canadians who did vote (which apparently has be the lowest number in history) thought the same way as my dad, and members of the NDP and Green Party lost seats under MMP.

The rest of the article then talks about how voting would change and how much "easier" it would be. It still sounds weird and if the majority of Canada's population don't see a problem with our electoral system, why then do we still need to reinforce the new referendum? Just because it worked in New Zealand, doesn't necessarily mean it'll work here.
