NZFFD assistant software

The NZFFD assistant software is available free to allow users to easily enter new data and submit them for inclusion in the NZFFD.

In addition, it can be used to display retrieved or entered data on a New Zealand map. It is a mini database, mapping, and graphics system rolled into one. It does not have all the features and complexity of large database, GIS, or graphics systems but because of this it is easy to use.

Free Download

The NZFFD Assistant software is available for Windows users to download as a compressed zip file. You must extract the files before using the assistant. We have tested it on Windows 98, NT 4, ME and XP, however, it is not a network application. If you have any problems extracting or using these files, please contact the NZFFD Administrator for assistance, contact details at the bottom of this paage.

  • Data entered are checked to ensure that field values are within reasonable ranges, correct codes are entered, and map references are correct.
  • A list of river names, catchment names, catchment numbers and map numbers that are used in the freshwater fish database.
  • Help on common, scientific and code names for all New Zealand freshwater fish species.
  • Help on catchment names, catchment numbers, and river names sorted by name, map number, or catchment number.
  • Database files can be retrieved and edited, and sent electronically to the database administrator for storage in the national database.
  • Records can be printed in the standard freshwater fish database form as a hard copy.
  • Records can be read from several file formats, such as a text file saved after a search of the freshwater fish database
  • Data can be copied to the clipboard and pasted into applications, such as Microsoft Excel, or can be saved as a comma delimited (CSV) file.


The map of New Zealand is based on the New Zealand map grid and shows the coast, islands, lakes, rivers, major urban areas, state highways, and regional boundaries.

  • North and South Islands can be displayed individually or together.
  • Optional display of rivers, roads, urban areas, regional boundaries, latitude and longitude, and scale.
  • Rivers and lakes can be displayed to seven levels of detail.
  • Zoom in and out on areas of interest.
  • Line and fill colours can be set.
  • The compass rose and scale can be moved or deleted.

Database records can be displayed on the map of New Zealand to check that their locations are correctly recorded or to produce distribution maps such as those used in our online Freshwater Fish Atlas.

The locations of database records are displayed as symbols (squares, circles, crosses, etc) on the map.

Maps can be displayed showing:

  • all sampling locations
  • locations where a particular species was found
  • locations where the species was found, with different symbols for locations that were sampled and the species not found
  • The size, colour and type of symbol can be set
  • The record number, card number, or location name of the sampling locations can be shown
  • The distributions of several species can be shown with different symbols for each species, by successively “saving” each species map.

The base map data on rivers, lakes, islands etc. can be updated by the database administrator as more geographic data become available. If users supply coordinates of relevant features that are not shown on the map, these can be added to the base data for the benefit of all users.

Text files containing a list of map grid references or latitude and longitude can be “imported” and displayed on the map as points, connected points (polylines), or polygons. Text files of points can also contain a name that is displayed alongside the point. For example, a file of map references and names for towns and cities could be imported and displayed on the map. Similarly, imported files could be used to display boundaries or new roads as polylines.


The graphics features allow maps to be annotated by adding:

  • lines or arrows
  • symbols (square, circle, cross, plus, triangle)
  • text.

Other graphics features include:

  • points, text, lines, and arrows can be moved, deleted or their size and colour can be changed
  • annotated maps can be saved and later “restored”, displayed, and edited
  • maps can be printed, saved as Windows metafiles, or copied to the clipboard and pasted into other Windows applications.
