About purchase units
A purchase unit is part of a classification system used to consistently measure, quantify and value a service. The purchase unit data dictionary (PUDD) is a spreadsheet that contains all purchase units for the counting of and contracting for health and disability services.
The PUDD includes the following information.

- Tab c – definitions for units of measure, inter-district flow (IDF) units of measure and output classes (the same as contained in DHB annual plans).
- Tab d – links to nationwide service specifications that must be used when using certain purchase units in contracts.
- Tab e – is a combination of any changes made to the latest version of the PUDD.
- Tab f – PU codes for National Non-admitted Patient Data Collection (NNPAC).
- Ministry only purchase units.
- Acronyms and Abbreviations used in the PUDD.
- Mapping tables for:
