Not at all. NZ plugs are the same design as Australian ones and mine seem quite capable of carrying a reasonable amount of weight - I have never ever seen one of our plugs fail under anything resembling sensible use. They're quite capable of carrying, say, a hefty attached transformer. And since the pins are angled, even a two-pin version is pretty hard to accidentally wiggle free compared to the two round pin European plug (I think some European countries have extra bits as well that might help?). Definitely does not deserve comparison to the awful American plug design.
