If your medical has been referred to be looked at by a Medical Assessor (MA), it will have gone into a date order queue upon arrival in their office, to wait its turn to be seen.
Medicals are first scanned by computer, and it's if there's anything marked as outside the normal that it has to be looked at by a human. The MAs are a separate department - it's their job to understand an applicant's state of health, to try to be sure that they won't cost the NZ health service too much for treatment or medication.
