Hager named his squad of 16 for the Games yesterday, omitting young striker Michaela Curtis and goalkeeper Bianca Russell from the 18 who contested the World Cup.
An audition is looming to settle on a back-up goalkeeper for Sally Rutherford. Most teams opt for just one keeper, preferring not to sacrifice an extra outfielder.
Russell will be in Ireland where the squad have a pre-Games tournament and will stay and train there. But once the opening day arrives, the 16 are locked in.
"We'll put a bit of a feeler out to the group. We've got three weeks to give them a bit of an opportunity," Hager said.
He's not expecting miracles -- "all we want is the basics, if they can stop the ball".
Captain Kayla Whitelock felt the disappointment of finishing second at Delhi four years ago, beaten to the gold by Australia in a penalty shootout.
"I certainly want to finish one better than my last Games," she said yesterday.
New Zealand are back up to fourth in the latest world rankings. They play South Africa (11th), India (13th), Canada (22nd) and Trinidad and Tobago (31st) in pool play.
Second-ranked Australia, with whom they drew 0-0 at the World Cup, and sixth-ranked England shape up as their biggest medal rivals.
New Zealand have a four-nation tournament in Dublin - playing hosts Ireland, Chile and Canada - from July 12 to 16 before going into the athletes' village.
Yesterday's announcement means the men's Black Sticks and the seven rugby team are the only athletes still to be named for a New Zealand team expected to number 235.
