N.M. Stat. § 18-6-12
A cultural property which the committee thinks may be worthy of preservation may be included on the official register on a temporary basis for not more than one year, during which time the committee shall investigate the property and make a determination as to whether it may be permanently placed on the official register. If the cultural property is on private land, the temporary classification shall not be considered a taking of private property, but the owner may receive a fair rental value for the part of the land affected if the temporary classification unduly interferes with the owner's normal use of the land. The owner shall be immediately notified of the committee's determination. If at the expiration of one year from the time the temporary classification was imposed the owner has not been notified of any committee action, the temporary classification shall lapse, and it shall not be renewed for five years.
