i know im late to reply but..i was just reading one of my old nz norml magazines,and,yeah it does sound like that they will destroy the seeds then send you a warning letter,and worse customs turn up at your house and ask a few questions.
The norml zine said "use a different name, and don't grow at the address you get them sent to".Of course i didnt do any of that apart from the slight change of address ...will let ya know the consequences.
seems that post was in january id like to know how you got on Hippy Birdman
