New Zealanders have until Friday to have their say on whether the North and South Islands should also be known by their Maori names.
People are being asked by the Geographic Board if the North Island should be called Te Ika a Maui and the South Island Te Waipounamu.
The question dovetails with this year's Maori Language week, which explores Maori names, including place names.
Chair of the Geographic Board, Dr Don Grant, says about 500 submissions had been received.
He says after submissions close on Friday July 5 the board will consider the feedback.
Dr Grant says the final decision on the names will be left to the minister of land information.
