Smoke damage has seen half of the Kiwi Ferns' team lose training gear and personal items after an incident at their training ground in England.
The incident came just 48 hours before their first match of their Rugby League World Cup campaign against France.
No-one was present in the affected area at the time.
"It's been tough for the girls," Kiwi Ferns coach Ricky Henry said.
"Some have gone well over 24 hours without being able to contact loved ones, unless through a staff member's phone.
"Sometimes these freak accidents happen, and this one was out of anyone's control. New Zealand Rugby League (NZRL) are working to replace the damage, and as a team, we will rally together, support each other and focus on what's ahead."
NZRL chief executive Greg Peters said it was an "unfortunate incident" which was quickly dealt with.
"The training ground are in the process of bringing facilities back online. No outdoor facilities have been affected and the staff at the training ground have been exceptional in supporting us.
"In the meantime, our main priority is the Fern's wellbeing and ensuring the team is supported through this."
The Kiwi Ferns were set to face France at 6am (NZ time) on Thursday.
