While profoundly Deaf politicians are rare, NZ has had a few nearly-deaf role models. Heather Simpson is probably the most powerful Deaf person in the country. Former Act MP Gerry Eckhoff wore two aids, which is why I was so stunned when Act voted against the NZSL Bill.
Congratulations to Kim Robinson on standing for the Nelson - Marlborough DHB this year. I met Kim last year at Deaf Club after the NZ Sign Language Bill passed the Third Reading. My signing was, as still is, very rudimentary. For a Deaf dude, he understood me just fine. All the best.
