Bob, my apologies.
After doing some more digging you have covered yourself by declaring "clean genus Nicotiana" and being open with your declaration.
Even then, the seeds require assessment under biosecurity regulations.
Hell, you can read and read all the nonsense regulations and still come out confused. It's just mind boggling.
In n.z. anything that is living or has the potential to live is treated very seriously when imported and that includes anything made of wood. Anything that has the ability to harbor disease or insects etc will be destroyed or treated at the recipients expense.
