All the former Dominions have a real lasting link with "the Mother Country"; there's no need or call for getting rid of this beyond the usual childish "anti-imperialist" elements. Even Key doesn't really want this. 110 years of history don't need to go on the pyre just because ADD leftie kids have distracted themselves from last month's fad of wanting to name everything after Nelson Mandela to this "anti-colonialist" crap.
As for the poster who asked "I think if you asked MOST NZ'ders which symbol they relate to, the Union Jack or the Fern?" - if you actually take a look at the NZ flag, it isn't simply a Union Jack.
So, do you think Canada should go back to the red ensign then?
