Cooper was not offered a transtasman league contract this year as she battled back from injury, but was thrown a lifeline by the national selectors when she was invited to Silver Ferns trials this week.
The other change to the squad is the return of veteran midcourter Joline Henry, who missed last year's international season through pregnancy. Despite battling a few niggling injuries, Henry impressed during the trials and is on track to make her international return against Australia next month.
Silver Ferns coach Waimarama Taumaunu said she's pleased with the depth of talent in the squad and that those selected were chosen on form after impressing all week.
"It's always going to be a difficult decision to exclude some extremely talented players, but we are satisfied we have made the right choices," she said.
"We now need to look ahead and focus on the next challenge which is the New World Netball Series for the Constellation Cup against Australia which starts on September 15. We've got a lot of work to do before then," Taumaunu said.
The test line-up to face Australia in next month's Constellation Cup series will be named on August 26 following a week-long squad camp.
