In response to an email sent by Mr Bargh, Land Information New Zealand confirms the name Kahutara had been recorded as Kahautara in early maps and plans. The original spelling is recorded in documents dating back to 1894.
It appears the name changed to Kahutara on the NZ Map Series 13 in 1960.
LINZ suggested Mr Bargh propose the name change to the New Zealand Geographic Board.
LINZ said because Kahutara was a populated place, support for the restoration would be needed from the community and council, "as emergency issues and addressing standards may arise due to a spelling alteration".
They also suggested support from the local tangata whenua to support the proposal.
Mr Bargh advised Mrs Staples he had support from iwi for the name change and is seeking support from SWDC.
Mr Bargh could not be reached for comment yesterday.
