LINZ Geodetic database

Update: 17 April 2018

Local Vertical Datum Height Discrepancy

Local vertical datum heights were updated on 14 January 2018 based on the Kaikoura earthquake geophysical deformation model. However, a further refinement based on post-earthquake observations is planned and will be implemented in the next few months.
