Coach Glenn Moore said the selectors tried to keep an open mind sifting 50 training camp players into a manageable squad.
"There's always someone who impresses. You can put them in with better company and they shine out.
"We anticipated we could have eight to 10 new caps and that's the way it turned out. It was a case of looking at combinations and the style of game we want to play.
"[These tests] will be special, particularly at Eden Park. Players hold it dear that they get the opportunity to play a test at home with the All Blacks in front of their families."
Five-eighth Victoria Subritzky-Nafatali and prop Toka Natua were not selected due to respective knee and hamstring injuries. Both were World Cup winners.
"The intention is they will start playing through the NPC [Farah Palmer Cup] and be available for the end-of-year tour," Moore said.
The news is a further endorsement of fan sentiment which demanded the women's fifteens programme be better funded so players could rely less on day jobs to supplement their careers.
New Zealand Rugby chief executive Steve Tew presented a prudent outlook when the team arrived home from the World Cup.
"A number of these athletes play sevens. They're effectively professional because there is a full-time programme of activity for them to play and train for.
"Fifteens don't have that level of competition. We're isolated in New Zealand with only Australia close by.
"The reality is that the fifteens programme doesn't sustain a full-time athlete at this stage, but the game is growing quickly."
However, a rejigging of the balance sheet has fast-tracked a women's memorandum of understanding into being.
The contracts include a guaranteed retainer to train, assembly fees when they come together for Black Ferns camps, and medical and technical services.
