Winston Peters says this is because "some of the people who have come here who don't salute our flag, don't honour the values of our country, don't respect the people living here", which again shows how out of touch that fossil is. Real kiwis don't "salute the flag" unless they're in a job which requires it. Anyone who does is some sort of weirdo. We're not Americans, and we don't want to be like them.
But Winston is right about one thing: there are people here who don't honour the values of our country or respect the people living here. They're in the Beehive, running the place, doing shit like this. And the sooner we vote them out on their arses, the better.
