Hon CHRIS HIPKINS: There are still some issues to work through, including the fact that when we remove quarantine at our end, there will be a massive increase in the number of people travelling across the Tasman every single day, and we have to be in a position to provide some certainty about what will happen for those people in the event that the safe travel zone is suspended. It could well mean we have tens of thousands of people unable to travel home, and we need to be clear about what will happen in those circumstances.
