Hon CHRIS HIPKINS: Workers crossing the boundary will need to produce evidence of a test within the last seven days. The officials are working with employers about the easiest way to facilitate that. Ultimately, it would be good to get, as much as possible, an automated system for that. In the meantime, I suspect it is going to be a piece of paper that gets produced at a checkpoint. In terms of the turnaround time for tests, we'll be working hard with employers to make sure that testing is widely available to all those who need it, which may involve standing up additional testing sites, certainly involves using a variety of different testing methods, including saliva testing and nasopharyngeal and throat swabs.
