Gisborne is not an "official" name for the city, the New Zealand Geographic Board says.
It turns out that the name has not been gazetted and is regarded as a collected or recorded name.
"There is no record in the board's archives for either Gisborne or Turanga (the original Maori name, an abbreviation for Turanga-nui-a-kiwa)," New Zealand Geographic Board secretary Wendy Shaw said.
Many place names were classified as "recorded" and had "pseudo-official status".
The status of Gisborne as a place name is identical to that of the "North Island" and "South Island".
