I used Coppersmith in Seattle as my importer. They seemed to know the taxidermist in New Zealand who prepped my capes and antlers. The taxidermist made a crate for everything and shipped it over. I used Tyron Southward Taxidermy in Christchurch.
Jennifer House is who I dealt with at Coppersmith. She was awesome to deal with and made it easy. I will say that it ended up costing more than I anticipated to get everything back, but it all made it without trouble.
