Aftermath
Following the earthquake, the Ministry of Civil Defence & Emergency Management (MCDEM) issued a tsunami warning for parts of the north and east coasts of the North Island. Waves measuring 30 cm in height were recorded by tide gauges at East Cape and Great Barrier Island, and although the warning was later cancelled advisories remained in place for strong currents and abnormal sea level fluctuations.{{Cite web|url=http://www.radionz.co.nz/news/national/312348/east-cape-shake-increases-risk-of-big-quakes,-tsunami-threats|title=East Cape shake increases risk of big quakes, tsunami threats|date=1 September 2016|publisher=Radio New Zealand |access-date=4 September 2016}}
