N.H. Rev. Stat. § 103:15-a
Any permanent policeman accepting the provisions of this chapter who is, at the time of his death or disability, working for some other than his own police department or a component of the state or federal government on a temporary assignment shall be compensated as though he was working for his own department and shall receive the same benefits that would have accrued to him if he had been working for his own department, provided that the policeman was working with the knowledge and approval of his commanding officer, police chief, selectmen, or city or town manager. This section shall apply to any permanent policeman working under cover, on emergency duty or in a training capacity. In the event such temporary assignment should exceed 10 working days, it shall be the obligation of the receiving agency of the assignee to insure that all member and employer contributions as required by RSA 103 are properly transmitted to the New Hampshire retirement system.
