As a result of the magnitude 8.8 earthquake in Chile, there are tsunami warnings in place for effectively the whole of the NZ coastline, but particularly the east coast. There have been 1.5m waves through the Chathams, and smaller increases recorded in NZ. The key messages from Civil Defence are that this is serious, that later waves may get bigger, and people should stay away from beaches.
Civil Defence site has regular updates.
Our thoughts are with people in Chile effected by the quake. There have been a number of deaths, and many after shocks right across the country.
UPDATE: 11.29am It seems that surges have stabilised for now, but Civil Defence warn there may be higher waves over next 6-12 hours. 1m surge reported in Northland.
