N.M. Code R. § 22.600.6.11
At the request of the driver or the driver's representative, MVD or MVD's agent, any law enforcement officers subpoenaed as witnesses, or upon the hearing officer's own motion, the hearing officer may for good cause continue the hearing. Continuance requests shall be submitted to the administrative hearings office in writing prior to the scheduled hearing or on the record at the scheduled hearing. The hearing officer shall consider only those requests made in writing at least three working days prior to the scheduled hearing absent extraordinary circumstances that the requesting party could not have known earlier. Employees of the administrative hearings office scheduling unit or the chief hearing officer may grant or deny the request on behalf of the hearing officer. An order to grant or deny the request may be issued prior to the scheduled hearing or if there is insufficient time to issue an order prior to the scheduled hearing, the hearing officer may grant or deny the request on the record at the hearing. Regardless of the cited good cause or emergency circumstance supporting the continuance, no continuance request may be granted unless there is adequate time to provide notice to the parties, subpoena witnesses and conduct the rescheduled hearing within 90 days of the notice of revocation.
