N.H. Rev. Stat. Ann. § 669:49

A plurality of votes shall be sufficient to nominate a candidate for town office by caucus. After the caucus, certificates of nomination shall be made and shall indicate the name and domicile of each candidate, the office for which he is nominated and the political principles or party he represents, and shall be signed by the chairman and clerk of the caucus or convention; and, when practicable, such certificates of nomination shall be signed by each candidate; but the absence of the signature of the candidate shall not invalidate a certificate of nomination.
