The New Zealand Coordinate Conversions form can be used to convert coordinates between datums, projections and height coordinate systems used in New Zealand.

All coordinates refer to a specific reference surface, either a datum or a projection. Before 2 coordinates can be compared, they need to be in terms of the same reference surface. Changing coordinates between datums is a process called a conversion, and changing coordinates between projections is a transformation.
