N.H. Rev. Stat. § 53-G:8
A district member may vote to withdraw in the same manner as the vote for admission to the district. If a majority of the voters of a district member present and voting at a meeting duly warned for such purpose votes to withdraw from the district, the vote shall be certified by the clerk of that municipality and presented to the board. Thereafter, the board shall give notice to the remaining district members of the vote to withdraw and shall hold a meeting to determine if it is in the best interest of the district to continue to exist. Representatives of the district members shall be given an opportunity to be heard at such meeting together with any other interested persons. After such a meeting, the board may declare the district dissolved or it may declare that the district shall continue to exist despite the withdrawal of such member. The membership of the withdrawing municipality shall terminate after the vote to withdraw.
