These geological units comprised of gravel, sand and mud were wholly or partly deposited in the Holocene (in the last 11,700 years) as a result of water-borne alluvial floodplain and fan processes. The units are indicative of the extent of Holocene flooding events preserved in the sedimentary record.  These data have been extracted from the geological units layer of the digital 1:250 000 Geological Map of New Zealand NZL_GNS_250K_Geology 3rd edition (2020) published by GNS Science
