Those named for the Oceania Cup hockey tournament have the inside running for places at December's World League finals in Argentina.
And for the three uncapped players in the squad of 18, Canterbury striker Sophie Cocks, Midlands defender Brooke Neal and Auckland defender Liz Thompson, that provides a hefty incentive to grab their chances at this week's camp in Hamilton and when the Oceania Cup starts in Stratford next Wednesday.
"When you get good performances you like to reward them," Black Sticks coach Mark Hager said.
Cocks is a pacy attacker, Neal was, in Hager's words, "the rock" at the heart of New Zealand's defence at the junior World Cup in Germany in mid-year, while Thompson is adept in a range of defensive roles.
Thompson was one of the players who went to the junior World Cup to win selection in the senior squad. That trip was a significant learning experience for the 19-year-old Auckland University commerce student. More of that lies ahead.
