Importing wholeleaf into NZ works ok, but expect to wait at least 4 weeks to get it as there will most likely be a delay when it gets to customs and is sent for heat treatment. Heat treatment has gone up in price - was $45 last year. Shredders are available for about $250 for a decent machine but only cut .8 of a milimetre - closer to RYO than a pipe tobacco cut.
I've not ordered any whole leaf for a while as I have had better luck getting tins from overseaes suppliers.
Send me a PM if you want more details, I would rather not discuss it on an open forum.
