"He was a very good-looking man, he dressed beautifully and everyone would say that he was a real gentleman ... He was a delightful, charming, sweet man."
Mr Nathan was partially deaf from artillery training during World War II, when he was a lieutenant in the Pacific Islands.
He later set up the Dennis Nathan Educational Trust which funds education for people born deaf.
He also helped set up the local branch of international charity United Way in 1974. It collates donations and distributes money to welfare charities.
Born in Paris to a French mother and a New Zealand father, Mr Nathan spent most of his childhood in Manurewa but later lived in Epsom with his wife, May, who died in 1997, aged 84, and their three children.
