The MOT53-NZGD2000 grid enables the conversion of normal-orthometric heights from the Moturiki 1953 local vertical datum directly to New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights.
MOT53-NZGD2000 is published on a one arc-minute grid (approximately 1.8 kilometres) extending over the benchmarks that nominally define the extent of the Moturiki 1953 vertical datum (174.5° E to 178.26° E, 36.5° S to 40.7° S).
The conversion value is represented by the attribute “delta”, in metres.
This grid is a combination of New Zealand Quasigeoid 2016 NZGeoid2016 and the MOT53-NZVD2016 height conversion grid. Where NZGeoid2016 is the reference surface for the New Zealand Vertical Datum 2016 (NZVD2016), while the MOT53-NZVD2016 grid models the difference between the Moturiki 1953 vertical datum and NZVD2016 using the LINZ GPS-levelling marks.
More information on converting heights between vertical datums can be found on the LINZ website.

This index enables users to identify the extent of the relationship grids provided on LDS, which are used to convert heights provided in terms of one of 13 historic local vertical datums to NZVD2016.
The polygons comprising the index show the extent of the conversion grids.
Users can view the following polygon attributes:
Shape_VDR: Vertical Datum Relationship grid area
LVD: Local Vertical Datum
Control: Number of control marks used to compute the relationship grid
Mean: Mean vertical datum relationship value at control points
Std: Standard deviation of vertical datum relationship value at control points
Min: Minimum vertical datum relationship value at control points
Max: Maximum vertical datum relationship value at control points
Range: Range of vertical datum relationship value at control points
Ref: Reference control mark for the local vertical datum
Ref_value: Vertical datum relationship value at the reference mark
Grid: Formal grid id
Users should note that the values represented in this dataset have been calculated with the outliers excluded. These same outliers were excluded during the computation of the relationship grids, but were included when calculating the 95% confidence intervals
More information on converting heights between vertical datums can be found on the LINZ website.
