A moderate 5.318ML earthquake occurred on Saturday, June 12 2010 at 2:20 am NZST 100km to the south and was reported widely felt throughout the lower North Island and upper South Island. It is unclear if this larger event is related to the Cape Egmont swarm as the faults south of the Cape Egmont Fault Zone in the South Taranaki Bight have yet to be determined west of the Manaia Fault.
