No. It is more to find out what sites require them if our staff visit those sites. We need to know which ones to ensure we send staff that have chosen to maintain their pass.
I can't think what sites would now require them. Courts have thrown them out (in some circumstances) and given risk profile of covid now, and the number of vaccinated people who have fallen ill (and thus infectious) I can't see how a site could justify discrimination on the basis of health status.
I'm surveying all my clients that had them, and most have back saying they are not required anymore. Some are very slow to reply. Only DHBs and aged care facilities still require them as far as I've seen.
