Grainger Falls was first recorded by Andreas Reischek, an Austrian who
explored New Zealand in the 1880s. He named the waterfall after his
friend Alfred Grainger, my great grandfather. Its exact location was
established on the 6th of February 2006 by Dr David Richards and
myself. As the stream which drains Lake Hector and contains the falls
was unnamed, the NZ Geographic Naming Board called it Grainger Stream.
Grainger Falls and Stream are now recorded in the New Zealand
Gazetteer of Official Geographic Names. They are shown on the West
Cape (CF04) map which is part of the NZ Topo50 series.
