Rt Hon JACINDA ARDERN: The member conveniently left out that those briefings would have been around the International Air Transport Association development that was under way. Of course, New Zealand wanted to make sure that we were following the guidelines that were being worked through internationally to ensure that there was something that would be interoperable, so that's what that briefing was about. Of course, as I've said, we are specifically working on an option that we believe should have interoperability, but, at the moment, countries are working on their own passports, and so you're trying to get that dual purpose of having something that's readily available but also having something that will be useful when New Zealanders travel.
