When travelling internationally through Auckalnd Airport, you're allowed to take an empty bottle. However, the "Prohibited Items" list stated on the Avsec site is not explicit about glass items (see link below) or I haven't read it thoroughly. 
The reason I'm asking this it that I like to take a reusable bottle with me when I travel. I usually take advantage of the Koru lounge to save money on buying a drink whenever I feel thirsty.
However, it just occured to me that my new drinking bottle is made of glass (seriously, not a beer bottle). I'm assuming it's more than likely to be confiscated at the security checkpoint but I'm interested to know if anyone has tried to take any glass items as part of their carry-on baggage.
