Talking with my friend from New Zeeland, the story from over there seems to be that this is a move by the current Prime Minister to add something to his legacy, rather than a move by the New Zeelanders themselves.
Whilst there is a general feeling within the population about having a new flag, the motivations behind the referendum is simply the Prime Ministers personal glory and the process is viewed as a sham, especially as it was all decided by appointed bureaucrats with no experience design decisions or reflecting the views of the population, this re-enforcing the general feeling that the New Zeelanders themselves were locked out of the process.
Their opinion on the current flag choices were "They were created using clip-art".
