Structural work at the front and back of the pitch needs tidying up before New Zealand head to the World Cup in The Hague next month, according to captain Kayla Whitelock.
The Black Sticks, ranked fifth, lost 3-2 to China in the playoff for third on the final day of the Festival of Hockey in Hastings yesterday.
It was a disappointing result for the hosts at the inaugural tournament, who earlier lost 2-1 to world No7 China in round-robin play.
Soft goals were gifted away to the Chinese yesterday. They particularly found the defence porous down New Zealand's right side. New Zealand had penalty corner opportunities to equalise in the second half, but none were grabbed.
World No2 Argentina beat world No4 Australia 3-0 in the final, while Korea beat Japan 2-1 to decide fifth and sixth places.
