Hon CHRIS HIPKINS: We've had several conversations, not in the last couple of weeks, but we have been in contact with one another. I do fully understand his position and the position of the Australian Government. There is still some work to do at an official level, though, which is progressing as quickly as we can. There are still some logistical hurdles to get through: for example, making sure that the operational separation at the airport is not going to lead to increasing risk—that work is ongoing—making sure that the crew separation and plane separation arrangements for green and red zone travel are robust—that work is ongoing—making sure that all of the technical issues that might arise are fully addressed; and making sure that all of the appropriate regulatory regimes and all of the issues associated with that are addressed. There are some flow-on immigration issues that could arise from free travel that is suspended. We need to understand those and make sure that the technical fixes are put in place for all of those so that everybody knows what they can expect when they travel across the Tasman.
