Ms Brown (36), who ended her 61-test career with the Silver Ferns in 2014, will join former All Black Bryan Williams as an ambassador for the 2018 Masters Games.
Ms Brown told people at the launch, including Mayor Dave Cull, she was ''really honoured to get the call'' about becoming involved.
Growing up in Whanganui, Ms Brown knew many people involved with the games.
''I was that kid outside the tent while my parents were inside the tent running around.''
She was yet to compete in a games, but intended to next year.
However, people planning on entering netball or basketball teams need not fear seeing her on the court.
''If I could have got out of playing netball without running I would have. I hate it,''she said with a laugh.
In a bid to overcome her distaste for the activity, she planned to enter a running event.
Games manager Vicki Kestila said organisers were thrilled ''two national sports heroes'' would support games participants next year.
Last year about 5000 people competed in the games and interest shown by people at the World Masters Games in Auckland in April suggested next year would be bigger, she said.
''I attended the World Masters in Auckland and was inundated by people wanting to register for our games in 2018.
''I think we could see a large increase in out-of-towners this time.''
The 2018 games offer 60 sporting events and run from February3-12 in Dunedin.
