N.H. Rev. Stat. § 53-G:7
The board may authorize the inclusion of additional district members in the multi-town communications district upon such terms and conditions as it in its sole discretion shall deem to be fair, reasonable, and in the best interests of the district. The legislative body of any nonmember municipality which desires to be admitted to the district shall make application for admission to the board. The board shall determine the financial and operational effects that are likely to occur if such municipality is admitted and thereafter either grant or deny authority for admission of the petitioning municipality. If the board grants such authority, it shall also specify any terms and conditions, including financial obligations, upon which such admission is predicated. Upon resolution of the board, such applicant municipality shall become a district member.
