Hon Dr MEGAN WOODS: Private security guards who are subcontracted through the Aviation Security Service (Avsec) are one part of the layer of security that exists in our managed isolation and quarantine facilities. Of course, the operational lead of our facilities lies with the New Zealand Defence Force. We also have Avsec, we also have police, and then we do have subcontracted security guards. Obviously, it is not acceptable to have security guards falling asleep on the job, and this is the subject of an investigation that we are carrying out with site security assessments of all of the 31 managed isolation facilities. But the guarantee I can give New Zealanders is that we aren't putting all of our faith in one simple layer of security, that we have multiple layers of security within our facilities, and that is why they are doing the job they were set up to do, and that is to keep COVID inside of our facilities and not in our communities.
