Hey Stillcallozhome,
It was NZ ASL. I am on the road at the moment so I don't have the specific name but here is the number to their (ASL) main office that I got off their website. NZ Ph: 04 913 9812 The operator should be able to put you in touch with the right person. It is possible to sit the NZ exams here in the US but it is typcally done at a consulte or emabassy. I had to get special approval for my situation.
Hope this helps,
