N.H. Rev. Stat. Ann. § 155-B:7

If no answer is served, the governing body may move the court for the enforcement of the order. If such a motion is made the court may, upon the presentation of such evidence as it may require, affirm or modify the order and enter judgment accordingly, fixing a time after which the governing body may proceed with the enforcement of the order. The clerk of the court shall cause a copy of the judgment to be mailed forthwith to persons upon whom the original order was served.
