White Ferns coach Haidee Tiffen's pleasantly surprised by the standard of her first World Cup training camp.
Nineteen players were part of last week's initial squad camp at Lincoln in Christchurch, with a majority of players returning from a month-long break.
Tiffen said players returned refreshed and with clear intent.
"More of that mental break [is what] I think a lot of them appreciated and not picking up a bat or a ball but maintaining that fitness was fantastic to see," Tiffen said.
The squad will be cut to 15 after a second camp in Christchurch.
Tiffen says it's going to be a tough decision to make, as all players are fighting hard for their spots.
"It was great to see the whole squad completely focussed and they desperately want this - it's going to make our job really challenging to pick the final 15."
The finalised 15 player women's cricket squad was meant to be named this week, but has been pushed back to next month.
Tiffen said while she knows most of who she wants in her head, there's still some uncertainty lingering.
"We're pretty happy with where things are at it's just those last few places - it's around the balance of the side and making sure we have enough of the cover of the areas we feel that need whilst we're in England."
Tiffen says she also wants to give the injured trio of Sophie Devine, Leigh Kasperek and Maddy Green more time to prove their fitness before selection.
