A report and spatial data that updates the existing knowledge on the Extent of New Zealand’s Active Sand Dunes and:
• meets the standards required for a National Indicator used for Environmental Reporting, and
• is consistent with Statistics New Zealand’s tier one statistics.

The existing sand dune extent indicator, which needs to be updated, can be found here:

We are seeking a solution that identifies the current extent of active sand dunes that:
• uses a methodology which:
o provides both spatial and tabular data
o provides data comparable to the existing data sets
o uses a reliable and reproducible analytical approach that can be used both at a regional and national scale
o is consistent with the approaches being undertaken by regional councils and the Department of Conservation.
• produces a report in electronic format which:
o identifies the extent of active sand dunes in New Zealand
o clearly details the methodology used including the specifications, resolution and assumptions used and any limitations and constraints of the method
o provides GIS files and associated metadata.

This is a unique opportunity to provide information that will inform the New Zealand public and decision makers about the state of one of our rare ecosystems, sand dunes.
