The state Health Department that as of Dec. 6, town registrars had informed the state of 679 new marriages and 30 couples married legally out-of-state renewing their vows.
Of the new marriages, 461 of the couples already had civil unions or domestic partnerships in New Jersey.
There are lags in reporting the data, so the state's tally does not include all same-sex marriages.
The state's first same-sex marriages happened Oct. 21 after the state Supreme Court refused to overturn a lower court order to allow them.
The same day, Gov. Chris Christie announced he would stop the state's court fight against same-sex marriage.
