One of New Zealand's most successful coaches, Broughton has been named as the official festival ambassador for the event, running from November 1 to 8.
Up to 600 local, national and international netballers aged 35 and over will converge on the Southern Lakes District for the festival.
Fifty teams from Australia, Cook Islands, Vanuatu and New Zealand have entered so far.
Air New Zealand Events general manager Keith Robinson said he was "thrilled" to have Broughton, herself a former Golden Oldies player, on board.
"She is an absolute icon of the game and, of course, is held in such high esteem in the South.
"The netball will be so much fun and the associated functions will be something they will remember for a long time."
Broughton, who coached the Invercargill-based Southern Sting to seven national titles, said she was looking forward to the event.
"I have played in several Golden Oldies Festivals as a member of the Invercargill United Team.
"I played in the original one in Auckland and I certainly embrace the Golden Oldies concept and know the positive value it has on so many of our senior netballers and their involvement on and off the court.
"Golden Oldies netball provides an opportunity for women to remain actively involved in the game we love, to remain active and also to enjoy playing with friends and meeting new ones from around the world.
"To have so many netballers from around the world come to Queenstown is a real honour and I hope that local clubs will really take up the opportunity to become involved. I am really looking forward to it."
The November festival would be the 13th of its kind, with Golden Oldies netball catering for all playing abilities.
