N.M. Admin. Code § 11.21.2.31
Immediately following the counting of ballots, the election supervisor shall serve a tally of ballots upon one representative of each party. The tally shall show the number of votes cast for each labor organization listed on the ballot, the number of votes cast for no representation, the number challenged ballots, and the percentage of employees in the unit who cast ballots. The tally shall also state whether the results are conclusive, and, if so, what the conclusive vote is. If the tally shows that fewer than forty percent of the employees in the unit voted, or that the choice of "no representation" received fifty percent or more of the valid votes cast, then the tally shall reflect that no collective bargaining representation was selected.
