Tim Southee is auctioning off one of his shirts from the World Test Championship final victory against India, with the proceeds to raise money for eight-year-old Hollie Beattie.
Hollie was diagnosed with neuroblastoma, a very aggressive form of cancer when she was just five years old.
The shirt, signed by Southee and the rest of the Blackcaps' squad, has been placed on Trade Me, with bids already totalling more than $3500.
"My family first learned about Hollie's story a couple of years ago through the cricket community and I have always been struck by the Beattie family's perseverance, strength and positive attitude," Southee writes.
"Since hearing that Hollie required more treatment I have been trying to find a way to support in some small way."
Other Blackcaps, including Martin Guptill and Tom Blundell, have used special rainbow bat grips in order to help raise awareness for Hollie's treatment.
The auction closes on July 8.
Hollie's Givealittle has also raised more than $500,000 towards its $850,000 target.
