Hon CHRIS HIPKINS: Up until recently, each managed isolation facility managed a sign-in and sign-out system individual to that facility. Since earlier this year, a "who's on site" digitised system has been rolled out across all of the managed isolation facilities. That has recorded who's on site at any given time. However, it would appear that there have been some issues with whether people have all been using that. In the case of case B, for example, it would appear that the person had not always been signing in when they had been at work.
