An immigration officer may request a Medical Certificate and a Chest X-ray Certificate to be provided for
any temporary entry class visa application if this is considered necessary to ascertain whether or not the applicant has an acceptable standard of health, despite any provisions exempting the applicant from having to provide a Medical Certificate or a Chest X-ray Certificate to support a temporary entry class visa application (
A4.25(g))
In your instance, the recommendation from the INZ medical assessor is a documented risk factor (
A4.25(i)(iii)) that indicates that the applicant should be asked to provide an updated Medical Certificate or Chest X-ray Certificate even if not otherwise required.
