An advocacy group for blind Kiwis is criticising colourful artwork installed as part of a $400,000 road improvements trial in Takapuna, Newshub reports. The trial aims to improve Huron and Northcroft streets, but according to Blind Low Vision NZ chief executive John Mulka, colourful dots are dangerous for blind or low vision Kiwis as they could create confusion and/or disorientation.
