Download the single table WINZSupply file

This option, providing a file for use independently of WINZ, consisting of a Microsoft Access 97 database with a single table called WINZSupply. (Yes, even though WINZ 5.5 runs in Access 2002, we've kept the older format here for maximum compatibility.)

As in the example below, this table lists the official codes and names for all New Zealand drinking-water zones, plants and sources. Suitable as a reference lists for related work. (Note: Use stand-alone, or import into Excel. This file does not import into WINZ itself))
