Hi Philip,
I think that it depends on who you get at the receiving counter. In my experience here in NZ if you happen to be "served" by an over diligent person then you get the third degree. If you are lucky, then the parcel is accepted without any problem.
Luck of the draw.............

I recently old a 19th C spear head to a chap in NZ and their customs seized it and he had to get police clearance to take possession of a prohibited weapon. After 6 weeks it was cleared only to be delivered to the wrong address and sit in the rain for 9 days!!!!!!!!!!!! Good one NZ Post.
