Preparations have been better and more intensive than ever before, according to captain Kelly Mason who believes New Zealand can be highly competitive.
That said, Mason says New Zealand will be the only team at the event who don't train full-time.
"Right now the main goal is to use this as a stepping stone to see where we're at," Mason said.
Mason, 27 and a national representative for eight years, has been a professional, having spent two years playing in Russia and France after finishing at the University of Hawaii, but most of the New Zealand players hold down full-time jobs or study at university.
"That makes it difficult, but at the same time we are doing a lot more than we have in the past, and our girls are naturally talented," she said.
"So I don't see any reason why, if we continue what we are doing now, we can't beat these teams and eventually qualify for the Olympics."
