New Zealand are requiring improvements at the Fast 5 World Netball World Series in Melbourne.
The six-time tournament champions have finished day one with one win and two losses, mixing defeats to England and Australia with a win over South Africa.
It was the second half which caused the most problems for the Fast 5 Ferns, with uninspired efforts in the final two periods resulting in their two defeats.
The most glaring was in their 37-30 defeat to England. It was a dire finish for the Ferns, who scored four points in the second half, with England utilising their power play - which sees all points doubled - to come from 26-16 down to claim the win.
The Ferns used their power play in the second quarter, winning it 20-7, with Ameliaranne Ekenasio by far their most prolific shooter, racking up 24 of their 30 points, including 16 in the power play.
