N.J. Stat. § 19:63-23
On an ongoing basis as each action is completed, the county clerk shall mark in the Statewide voter registration system, which will be shared with the free-access system, to show that mail-in ballots were delivered or forwarded to the respective registered voters. For each mail-in ballot that has been voted, received and counted, the board of elections shall also, by reference to the certificates removed from the inner envelopes of such ballots, place the word "Voted" in the space provided in the Statewide voter registration system and duplicate voting record for recording the ballot number of the voter's ballot in the election. For each mail-in ballot that has been voted, received and rejected pursuant to section 17 of P.L. 2009, c. 79(C.19:63-17), the board of elections shall mark as "Rejected" in the Statewide voter registration system, which will be shared with the free-access system. For each of the rejected mail-in ballots where the voter provided a cure and therefore were accepted, the board of elections shall provide an additional input as "Accepted" in the Statewide voter registration system, which will be shared with the free access system. In the case of the primary election for the general election, the board shall also cause to be noted in the proper space of the Statewide voter registration system or other record of voting form the first three letters of the name of the political party primary in which such ballot was voted. The record contained in the Statewide voter registration system and of voting forms in the original permanent registration binders shall be conformed to the foregoing entries in the duplicate forms.
