Update: 1:45PM THE Silver Ferns' shooting depth could be tested in their crunch pool match against Jamaica at the Commonwealth Games.
Maria Tutaia and Cathrine Latu, their top shooting combination, are both in doubt for the final-round clash in Glasgow on Wednesday, which will determine who wins the group.
Both sat out the 88-19 victory over St Lucia on Tuesday after being injured in New Zealand's previous game against Northern Ireland on Sunday.
Tutaia, who has a foot problem, watched on wearing a moonboot as a precaution, while Latu has a calf issue.
Coach Waimarama Taumaunu says it's a case of wait-and-see with both players.
"We're working as hard as we can to try to get them back on the court," she told NZ Newswire.
"That's day-by-day at this stage."
Taumaunu rated both as doubtful to face Jamaica, who like New Zealand are unbeaten.
But she was hopeful they would be right for the semi-finals on Saturday.
"You don't want to have injuries at the best of times," she said.
"It just affects the depth of your group and the variety of line-up."
The Silver Ferns were forced to start Jodi Brown at goal shoot and usual mid-courter Liana Leota at goal attack against St Lucia.
Taumaunu continued to mix up her line-up during the contest, moving defender Joline Henry to centre and Laura Langman to wing attack.
One bright spot for New Zealand on the injury front came with the introduction of shooter Ellen Halpenny in the fourth quarter.
Halpenny came through the 15 minutes to show had got over the ankle sprain she picked up on her Test debut against Scotland on Saturday.
