The squad for the Oceania Cup will be confirmed at the end of next week. That tournament, in Stratford from October 21-25, is crucial for New Zealand.
They must beat world No 1 Australia to advance to the Rio Olympics next year. The women's Black Sticks have already secured their spot in Rio.
The only uncapped player is Midlands versatile Matt Rees-Gibbs.
''He played very well last year more as a striker, this year he performed pretty well in midfield," Batch said.

''We're thinking of him as a striker. He's very collective in his play. He understands the pressing side of the game and we'll throw him in and see what he can do."
India, ranked eighth, one spot lower than New Zealand, were the first team to qualify for Rio and Batch expects they will present a quality challenge.
''They are pretty strong on penalty corner attacks and renowned as a fast, attacking team, similar to Australia in that respect. We've got to manage that situation pretty well," Batch said.
A New Zealand invitation team is also playing two games against India, this afternoon and tomorrow at North Harbour, which will also go into the mixer to help Batch make his final selection for the Oceania Cup.
New Zealand play India in Nelson on Tuesday and Wednesday, and in Christchurch on Friday and Saturday.
