Previous works devoted to the Ne V spectrum are very fragmentary and yield a rather controversial picture of this ion. A lot of unidentified lines are still reported in these multiple studies. In the present paper, Hartree-Fock calculations and least-squares fits over the whole set of the available data (including the most recent ones) have been performed. As a result, a comprehensive view of the Ne V spectrum is presented. 10 new energy levels and 40 newly classified lines are proposed. An improved value of the ionisation potential of Ne V is also proposed.
