The Kaikoura earthquake of 23:02 on the 13 November 2016 impacted on a number of stations in the central part of New Zealand. Because of this the hourly height values for several stations from 14th November 00:00hrs have been adjusted by LINZ. For station Timaru the adjust is -0.008m.

The adjustment due to the Kaikōura earthquake of 2016 has been removed as relative sea level series should include land movement.
