Head coach Colin Batch said despite several injuries within the squad it was pleasing to have strong players ready to step up.
"We have some injuries at present with Nick Wilson, Shay Neal and James Coughlan all sidelined, but have created good depth and are still able to put out a very good side for Argentina," he said.
That depth has led to a few role changes in this team with Phil Burrows moving back up to striker and Shea McAleese pushing back into defence.
"Steve Edwards will also move into the attacking line. He is a very talented player with great attacking skills and we think he can be genuine goal scoring threat."
New Zealand is joined in Pool A at the tournament by Netherlands, Korea, Japan and Egypt while Pool B consists of Germany, Argentina, Spain, Canada and Austria.
The World League format sees the Kiwis play four pool games ahead of a crucial sudden-death quarter final against a Pool B opponent.
