(1) The Minister may, by notice in the Gazette, require all persons within any part of New Zealand specified in such notice, wherein an outbreak of smallpox has occurred, or threatens to occur, forthwith to be vaccinated or revaccinated.
(2) In every such case the Medical Officer of Health may appoint convenient places as vaccination stations, at which vaccination shall be performed free of charge.
(3) Where any medical practitioner is of opinion that any person required to be vaccinated pursuant to these regulations is not in a fit state of health to be successfully vaccinated, or for any reason cannot be safely vaccinated, then in lieu of performing the operation he shall give the person, or where such person is a child, the parent or guardian thereof, a certificate of postponement under his hand in form 3 in Schedule 1 hereto.
(4) The period of postponement named in the certificate shall not exceed two months from the date thereof; but at any time before the expiration of such period a fresh certificate may be given for any period not exceeding two months. Certificates may be given from time to time and as often as the medical practitioner thinks fit, having regard to the circumstances of the case.
