The (1994) Arthur's Pass earthquake (Mw 6.7, South Island, New Zealand) had a
complex aftershock sequence including events aligned with major mapped faults. To deter-
mine whether the major NESW-trending strike-slip faults in the region were activated
during this aftershock sequence, we investigate the largest well-recorded aftershocks.
