Those given the job of running the flag project had a critical yet simple guide for any flag.
"A great flag should be distinctive and so simple it can be drawn by a child from memory," they wrote in a letter to the public.
So the Herald asked a class of children at Avondale Primary School in Auckland to search their memories and draw the New Zealand flag - either the current version or one of the proposed new alternatives.
There was no direct preparation other than teacher Bill McCutcheon telling his class of children aged 8-9 that a reporter from the Herald was coming to talk to them about the flag change referendum.
The results of an entirely unscientific poll were enlightening - but not that surprising after interviews with a children's art teacher and a developmental psychologist.
