Growing up in Mangere, the child of wealthy landed gentry, Flora could never have guessed her sheltered life would turn out the way that it did. Her adult life started with a stint as a nurse, but she quickly discovered fashion was her passion and became the proprietor and designer of Ninette Gowns "the finest dress salon in the Pacific".
Flora's role in the war effort was entertaining the visiting American troops. Once money changed hands a business was born: a new business for Flora, but the oldest one in the book.
The beautiful models at Ninette easily made the transition from mannequins to Madam's Girls in Auckland's Ring Terrace. Flora saw no harm in her new career, she was simply giving people what they wanted. But the times, people, and ultimately the police, were not inclined to be kind.
On her death, at her home on July 8, 1982, she had cirrhosis of the liver and a weak heart. She had been ill and in pain for some years; she had never married nor borne children and was rumoured to have left her premises to the man who delivered her weekly crate of whisky.
All her money went to the deaf. Although no death notice was published and her funeral was a quiet affair, the obituaries and tributes to her were fond and numerous.
Amongst those who paid tribute to MacKenzie was one of her former legal counsel, Roger Maclaren, who said: "She was generous to a fault and always a sucker for a soft touch. She had an amazing sense of humour, she was garrulous, obscene - she was everything a madam should be, I suppose".
Famous Flora directed by Liz Sheppard and Lee Owens, on stage at Riverlea Theatre from April 13 till 27.
