We have prepared a quick guide that is designed to help guide you through all the common steps involved with downloading and uploading data. We suggest you save a copy of this overview and keep it handy for when you are next using the NZFFD.

- After you have registered and logged in to the database you can enter sampling data by clicking the "Enter new data".
- There are three compulsory fields on the "Sampling Event" tab, and one compulsory field on the "Catch Data" tab, which are highlighted with *.
- The sampling coordinates field displays your coordinates on a map and you can use this to select the nearest REC segment, called an NZSegment. This is easily done by entering your sampling coordinates or clicking on the map, then selecting the closest NZSegment from the options that appear on the right of the topographical map.
- All the remaining fields in the NZFFD webpages are optional, but we strongly urge you to enter as much information as you have available
After you have registered and logged in you can view the contents of a single card by entering the card number you are interested in into the "Record No." box and hit "Go".
We are currently developing a webpage that will allow you to download records and plot these, but this is not yet ready. We will update this section as soon as this is available.If you wish to display locations of NZFFD records we recommend using the free software "QGIS".
Not all of the data uploaded to the NZFFD is returned during searches. This is because some of formatting difficulties associated with fitting some data within a single column in Microsoft Excel. All of the data submitted is saved and is available to be downloaded.
Just email: [email protected] and explain what data you are after. Normally this is free of charge unless your request requires significant amounts of time. A charge may be incurred if a large amount of time is spent on your request, but you will be informed of the likely charge before the work is undertaken.
We have retained some functionality with the old NZFFD assistant software for users still wishing to use program, but we encourage you to use the new webpages available. The new webpages enable you to store more information about your sampling sites and also to directly upload data to the NZFFD.
If you have old records to upload that have been saved using the NZFFD assistant you can still upload these. After you have registered and logged in you can enter sampling data by clicking the "Upload new data from the Fish Assistant". Here you will need to upload a series of individual files created by the NZFFD assistant when you save your file. There are instructions at the bottom of this page to help guide you through this.
If you wish to use the NZFFD Assistant to display the locations of records, just ensure "Fish Assistant" is selected under "Download format". This can then be directly loaded into the NZFFD Assistant
