Sorry, I did not realise you were talking about NZ with the red poppies.

The red poppies are quite recent here in Australia for Anzac Day....they were always associated with Rememberance Day.  As far as I know all Australian states have the tradition of Rosemary for Anzac Day although it is definitely falling off since I was young.  My grandmother's generation who lived through WW1 always had it growing in their gardens...the bushes all got a good pruning in time for Anzac Day.
