This research group has now settled on the final version of the Geographic Classification for Health (GCH)


We thank all those who have contributed to this qualitative consultative process in developing these maps for use in Health research. 

The purpose of the GCH has been to classify all areas of Aotearoa New Zealand as rural or urban according to their proximity to larger urban areas employing population and drive time that are meaningful with respect to health.


Please view these maps in a PDF file format on the GCH maps page.  Geographic Classification for Health – GCH

GCH categories of SA1s in Te Ika-a-Māui/ North Island

GCH categories for SA1s in Te Waiponamu / South Island





Disclaimer: We are in the process of publishing a report so we ask that you refrain from publishing your research until the GCH tool has been published.  You are welcome to use the maps and concordance files to assist in your research or reviews.
