nhops.co.nz is the distributor over here,email doreen helms, they come in 1kg,5kg and 25kg, not sure what freight would do to the price.the last price list i had was nz$31.20 for 1kg,cheaper if you want more although i don't have those prices.
i'm guessing freight will kill the price from here but i'd be interested to see how these prices compare to what you guys can get!
