New Mexico Statutes Chapter 29. Law Enforcement § 29-11A-9. State preemption; saving clause

A. The state preempts the field of sex offender registration and notification. Cities, counties, home rule municipalities and other political subdivisions of the state are prohibited from adopting or continuing in effect any ordinance, rule, regulation, resolution or statute on sex offender registration and notification and from imposing any other restrictions on sex offenders that are not included in the Sex Offender Registration and Notification Act. The department, cities, counties, home rule municipalities and other political subdivisions of the state shall not require a sex offender to report or to register more frequently or to provide information not required by the Sex Offender Registration and Notification Act.

B. After January 18, 2005, cities, counties, home rule municipalities and other political subdivisions of the state are prohibited from adopting or amending an ordinance, rule, regulation or resolution on sex offender registration and notification. An ordinance in effect on January 18, 2005 shall continue in force and effect until repealed; provided that the ordinance shall only continue in force and effect with regard to sex offenders who are required to register pursuant to the provisions of the ordinance but who are not required to register pursuant to the provisions of the Sex Offender Registration and Notification Act. All other sex offenders shall register pursuant to the provisions of the Sex Offender Registration and Notification Act.
