I think when the New Zealanders talk about kiwis being their national emblem, they are talking about the bird and not the fruit.
Indeed, as the Royal New Zealand Air Force roundel demonstrates. Nobody in NZ refers to kiwifruit as a "kiwi". Note this is an RNZAF historic flight aircraft, we don't still use Harvards operationally
Pertinent to the discussion though is that the Kiwi roundel has only been in use since 1970. Prior to that from 1957 a different design was in use, at first in white, then silver:

here. The Harvard pic is mine.
Pre 1957 the standard RAF roundel was used but I don't know if many people know that the silver fern has already been used in an official government capacity to represent NZ, and it wasn't altogether successful for a variety of reasons, colloquially being said to resemble a white feather being one of them.
A history of the silver fern design and transition to kiwi is
here for anyone interested.
As for the flag, I'm not seeing any real public mandate or drive other than Prime Ministerial whim (not anything more significant at least than the other times this topic has surfaced as it periodically does in NZ) and that's not a good enough reason to change it, or spend 20-odd million bucks of public money in the process. That and the lack of a better design. The silver fern on a black flag? Gimme a break.
I don't care if people confuse the current flag with Australia's. It's not my problem if people aren't observant enough to notice the obvious differences and as others have pointed out there are other nations out there that share actually identical flags (or near enough) without a problem.
