UPDATED: The Ministry of Civil Defence & Emergency Management has convened this morning and have advised there is not likely to be a tsunami threat for New Zealand.
This is based on the revised magnitude (Mw 7.6), and depth of the earthquake, said the Ministry of Civil Defence
Some caution will still have to be given regarding potentially strong, unpredictable currents around coastal areas of New Zealand, the Ministry said.
This includes areas around the northwest part of the North Island, and based on past experience along the west coast of the South Island (e.g. Greymouth, Westport).
Travel times to the northern end of the North Island are approximately 4 hours, and to the west coast of the South Island approximately 6 hours.
However the Ministry of Civil Defence said they strongly advise caution over the next 24-48 hours.
