Miss Braumann, who will not reveal her age and jokes about being married to the stockbroking and financial advisory firm, is still happily working full-time, as a quality controller in the custody section, and has no intention of retiring.
She cannot believe so many years have passed since she joined the company, in 1961.
"I’ve enjoyed every minute of every day.
"I love getting up in the morning knowing another pleasurable day and work is ahead, and of course the great company of those that I share it with."
There was always something special about the firm, and she knew early on that the office was more than just a place of work, she said.
"There was a lovely family feeling between the partners and staff, and over the years the bond between the two grew stronger and stronger.
"Even at that terrible time of the crash [in 1987], everyone wanted to help each other, but what followed after the crash were very difficult times indeed for Michael Devereux, Eion Edgar and Michael Sidey, but we survived."
Another "huge" challenge was last year’s pandemic, when she and the firm’s staff were working from home using specially installed computers.
A keen competitive table tennis player in the 1960s and early 1970s, she won Otago, South Island and two national titles during her early years with the company.
When she joined Forsyth Barr & Co, as it was then, its office in Consultancy House, in Bond St, had three partners and five staff, and she brought the overall staff complement to nine.
The firm now had more than 425 staff working in 22 branches throughout the country, and provided portfolio management for more than $20billion of clients’ investments.
"A tremendous achievement and a long way from the small local firm of nine," she said.
Forsyth Barr chief executive Neil Paviour-Smith said Miss Braumann had been a pleasant and dependable employee through thick and thin.
A "wonderful, positive person", she was well-loved within the company, he said.
Someone working that long in one place was likely not unique, but it was certainly rare, and much appreciated.
Having started work in the time of company founder Robert Forsyth Barr, she had an unmatched institutional knowledge.
"She’s the source of truth within Forsyth Barr about what’s happened in the past."
To mark her ongoing contribution, one of the new boardrooms in Forsyth Barr House, which is being refurbished, would be named after Miss Braumann, Mr Paviour-Smith said.
