New Zealand medical experts warned that once authorities relax the health screening requirements for international students, it could lead to people infected with HIV and hepatitis being granted visas to study there.From July 2012, New Zealand student visa applicants will be screened only for tuberculosis, unless they have other health conditions they declare. Therefore, foreign students will no longer need to supply full medicals and the responsibility will rest on visa applicants to declare their health conditions rather than on medical checks to detect diseases.
