A "courageous" Wellington teenager, who spent the last week of her life raising hundreds of thousands of dollars for cancer research, has died.
Jemima Gazley was diagnosed with stage 4 brain cancer earlier this year and testing revealed it was both inoperable and incurable.
She lost consciousness late last week, her family said, and died peacefully on Tuesday evening.
Jemima and her family had been documenting her story through a Givealittle crowdfunding page, where she was raising funds for Australian cancer researcher Mat Dun. As of Wednesday morning, the campaign had raised about $446,500.
"To all our wonderful friends, poets, uplifters, supporters, wordsmiths and contributors - it is with a heavy heart to let you know Jemima's incredible journey on earth has come to an end," her family said in an update on Tuesday night.
"She passed away peacefully this evening and she wanted to let you all know that she is finally cured and free. She is dancing through the heavens, laughing and full of joy in her return to pure energy."
The family said Jemima's legacy would live on.
"With our most sincere gratitude and love - please know every one of you has made the final chapter her greatest triumph."
Earlier this week, Dr Dun told the NZ Herald Jemima's fundraising efforts were "incredible".
"I read her thoughts [on the Givealittle page] and was struck by how courageous and selfless she was being," he said.
"It's quite remarkable to think of a child that's able to sympathise with what's going on and really focus her efforts on the future," Dr Dun told the Herald.
