Thanks all, SWFA not an option here as far as I know.
NZ is one of the few countries that SWFA will export to. You can order direct.
Thanks for the heads up Jordan. This wasn't the case a few years ago when I looked into it so for once a change in our favour!
Yup, a couple of years ago SWFA made changes to the export policy removing Canada from the "go" list, and adding NZ.
