N.J. Stat. § 19:63-15
The commissioner of registration upon receipt of the information from the county clerk required by section 14 of P.L. 2009, c. 79(C.19:63-14) shall mark the applicant's record in the Statewide voter registration system and duplicate voting record appearing on the signature copy registers as follows.
Whenever the commissioner of registration receives from the county clerk notice that a mail-in ballot has been forwarded to a voter during the time when the signature copy registers are in the custody of other election officials pursuant to current law, or are in transit to or from such officials, the commissioner shall, prior to the opening of the polls on election day, forward to each polling place a list of all such voters to whom ballots have been sent but whose duplicate voting record has not been marked in the manner herein prescribed. Such lists may be prepared in the same manner as a challenge sheet and may be included therein together with other causes for challenge. Any person whose name appears on any list or notice furnished by the commissioner of registration to the effect that such voter has received a mail-in ballot, but who wishes nevertheless to vote at the polls on the day of an election, shall be permitted to vote by provisional ballot after completing the affirmation statement attached to the envelope provided with the provisional ballot pursuant to section 7 of P.L. 1999, c. 232(C.19:53C-1).
Whenever a mail-in ballot has been delivered to a voter less than seven days before an election and up to 3 p.m. of the day before the election, and the signature copy registers are in the custody of other election officials, or in transit to or from such officials, the county clerk shall prepare a master list of all such ballots, and the list shall be transmitted to the commissioner of registration in sufficient time to permit the commissioner to notify the appropriate municipal clerk. The clerk shall notify the judge of the polling place to mark the voter's record accordingly.
