The Seismological Observatory, Wellington, is often asked to supply lists
 of earthquakes that have occurred in particular geographical areas of New
 Zealand, near certain towns or planned construction sites, or chosen on other criteria. In the past the preparation of such a list has necessitated a time-consuming examination of the printed Bulletins and other less accessible records. This procedure has now been greatly simplified by
 the preparation of a master file of earthquakes known to have occurred in the New Zealand region. This file contains over 13,000 earthquake origins and is stored on magnetic tape for use on the Burroughs
 B6700 computer at the Victoria University
of Wellington.
