It's a team brimming with experience and talent, including five players who have played more than 200 internationals for their country. The players were welcomed to the Olympic team at an announcement event co-hosted by the New Zealand Olympic Committee and Hockey New Zealand in Mount Eden this afternoon.
Talismanic midfielder Whitelock (247 tests) will suit up for her fourth Olympic Games having already competed at Athens 2004, Beijing 2008 and London 2012.
Meanwhile Rio signals a third campaign for Gemma Flynn who first played at the Beijing Games as an 18-year-old, while Anita McLaren, Sam Charlton, Stacey Michelsen and Charlotte Harrison all head to their second Olympic Games having competed at London 2012.
Only three of the 16 players selected have played less than 100 games - defender Brooke Neal (88 tests) and strikers Kirsten Pearce (54) and Smith (20).
Capital's Smith is the bolter of the group, having been rewarded for her impressive performances at the International Hockey Open in Darwin and Champions Trophy in London earlier this year.
Smith is one of three hugely talented 21-year-olds in the team alongside Canterbury striker Sophie Cocks and Auckland defender Liz Thompson.
The team will be captained by Whitelock, with support from a leadership group which includes McLaren, Michelsen and Charlton.
New Zealand's most capped women's player of all-time Gaddum (274 tests) was unavailable for selection due to pregnancy with her first child.
Head coach Mark Hager said the team selected is very well balanced with a lot of experience and confidence.
"We're taking away a very strong team, it's well balanced and contains some great experience with six players who have been to an Olympic Games before, along with plenty of Commonwealth Games and World Cup experience," Hager said.
"This team is capable of medalling and we have proven over recent times that we can win in those high pressure situations which we will certainly face in Rio."
