@NZcivildefence That took 49 minutes. If there was a tsunami, it would have been too late. The wave travels around 600 to 700km per hour. Not impressed.
There is no tsunami threat to New Zealand following the M7.4 SOUTH OF THE KERMADEC ISLANDS earthquake. Based on current information, the initial assessment is that the earthquake is unlikely to have caused a tsunami that will pose a threat to New Zealand.
