The decision brings an end to a highly decorated career where van Dyk played a world record 217 Tests for her native South Africa and New Zealand, shooting 5917 goals at 90 per cent accuracy and competing at five netball world championships and four Commonwealth Games.
Alexander said van Dyk has been an iconic figure in the sport since making her international debut in 1994 for her native South Africa.
“Irene has been an inspiration to netballers around the world through her professionalism and the spirit with which she has competed for both South Africa and New Zealand,” Alexander said.
“It was always a highlight of every Silver Ferns Test against the Diamonds over the past 14 years to see the contest between Irene and the likes of Liz Ellis, Susan Furhmann and our current captain Laura Geitz.
“I wish Irene and her family all the best for their future endeavors.”
Ellis, a former Australian captain, paid tribute to van Dyk’s brilliant career on Twitter.
“Sad to see you retire from @SilverFernsNZ – honoured to have played against you,” Ellis tweeted.
Van Dyk, who turns 42 later this month, has indicated she will continue playing in the ANZ Championship next season.
The Silver Ferns are set to announce their squad for the upcoming Glasgow Commonwealth Games next week.
