Following an unpleasant encounter on a Wellington bus earlier in the week, advocates for blind and low-vision people are calling for improved awareness and understanding of what life is like for the vision impaired. George Taggart told Checkpoint he wasn't allowed to board a bus on Adelaide Road on Wednesday when the driver didn't believe that his poodle, Gus, was his guide dog. The council's transit agency Metlink has apologised, but Blind Low Vision New Zealand argue there's a major lack of understanding in the wider community about what life is like for the vision impaired. The organisation's chief executive is John Mulka. He speaks to Susie Ferguson.
