From update 19 - Tsunami Warning still in effect

The arrival of waves has been tracked by the tidal guages at the New Zealand coast. For locations in the North Island, tsunami waves of amplitudes up to 70 cm continue to be recorded. There have also been reports of significant tidal fluctuations. The Chatham Islands has recorded sea level changes in excess of 1 metre. Modelling of this event suggests that the amplitude of the waves should now begin to decrease. MCDEM and scientific advisors are closely monitoring the situation and will be reviewing the level of threat over the next couple of hours.
