We have read that NZ is very strict about how you bring in your drugs/medications, i.e., that they should all be in their original containers. Usually we place our medications, vitamins, and supplements in a compact compartmental container that doesn't take up much room in our carry-ons. We have not had any problems anywhere else we have traveled. Our prescribed medications don't take up much space, but we buy our supplements and vitamins in larger containers. How big an issue is this? Does anyone have any experience with this issue?
