The archive contains scanned images of published and unpublished, geological maps for New Zealand, its offshore territories and Antarctica. The maps range from field sheets to draft compilations to complete maps as published. The collection includes maps dating back to the mid 19th century until 2012. The hardcopy maps are stored in an archive facility at GNS Science's Lower Hutt building and some of the oldest maps are stored with the National Library. Most maps in the collection are available in digital formats; hardcopy maps have been scanned in high resolution during the 2010s, georeferenced and made available through a map image server. These maps represent the pre-2012 component of the Regional Geological Map Archive and Datafile, one of New Zealand Nationally Significant Collections and Databases, and complement more recent digital geological maps available from the Geological Map of New Zealand repository.

The Regional Geological Map and Data File (RGMAD) is a Nationally Significant Database and Collection for which GNS Science has custodianship. RGMAD is an archive of published and unpublished, hardcopy, and digital image and digital GIS format file geological maps for New Zealand, its offshore territories and Antarctica. The maps range from field sheets to draft compilations to complete maps as published. The collection includes maps dating back to the mid 19th century until the present and is regularly added to when new geological maps are completed. The hardcopy maps are stored in an archive facility at GNS Science's Lower Hutt building and some of the oldest maps are stored with the National Library. Most maps in the collection are available in digital formats; hardcopy maps have been scanned in high resolution during the 2010s, georeferenced and made available through a map image server. Vector GIS format maps created since the mid 1990s are stored on GNS Science servers and are available through web services and physical media sales.
