Document Status: Superceded
Document Number: 25004

Document Type: Standards
Published date: 15 September 2009

NZVD2009 normal-orthometric heights are measured above the New Zealand Quasigeoid 2009 (NZGeoid2009) surface. The standard defines offsets to 13 existing local vertical datums so that heights can be consistently converted between them, NZVD2009 and the NZGD2000 ellipsoidal height system.

Note: This Standard has been superseded by the Standard for New Zealand Vertical Datum 2016 - LINZS25009.
