''We are doing a lot of things well but still need be more desperate in defence and need to convert some of our opportunities, that's for sure."
Batch said the statistics were showing New Zealand are creating plenty of opportunities, having more shots on goal and penalty corner chances. That is a positive aspect of the Black Sticks' work at present.
New Zealand are without regular striker Hugo Inglis, who flew home after New Zealand's three-game series against the Netherlands last week, with a small tear in a calf.
''His medical support and treatment back there would be the best it can be. We think he'll be right and back to full training almost by the time we get home," Batch said.
New Zealand next face world No 3 Germany early tomorrow.
In today's other two first-day matches, Argentina beat Ireland 1-0 while the Germans beat India 4-0.
