The 34-year-old played a fundamental role in the Silver Ferns' success since she first slipped on the black dress. She didn't miss a game in her first 141 tests between 2005 and 2016, captaining the team through some of their most successful campaigns.
Langman retires with 163 test caps (the most in New Zealand netball history) and steps down having won all major netball titles, including last year's Netball World Cup.
She started her domestic netball career with the Waikato Bay of Plenty Magic from 2003 to 2012 before moving to the Northern Mystics.
She then headed to Australia with the New South Wales Swifts and recently captained the Sunshine Coast Lightning in the latest Super Netball championship.
Langman called time on her Silver Ferns career in August.
