Jools was one half of the legendary folk duo The Topp Twins alongside Lynda, their career in comedy, music and activism spanning more than four decades.
She had lived with breast cancer since 2006, publicly sharing her experience with the disease for much of that time.
Lynda shared Jools’ final message to New Zealanders with 1News last month, thanking the country for “being there” for the pair.

“We couldn’t have done it without you. You made us who we are, you made us the Topp Twins.”
Wearing Jools’ greenstone pendant, Lynda said her “very special twin sister” had lived a good life and had a good death surrounded by family.
“Tonight, I ask every single one of you out there in New Zealand to hold your loved ones close.
“And for every person out there and family that are going through cancer, to be there for them, and love them, and hold them in your hearts.”
The sisters were widely regarded as national treasures, admired for their humour, advocacy and Kiwi-style performances.
An outpouring of grief and tributes followed the news of Jools’ death.
Her family led the tributes as they announced her death on May 26, describing her as a “beloved sister and daughter”.
“Today we have lost a true warrior woman. Jools was wise, courageous, generous, inspiring and funny.”
Former Prime Minister Dame Jacinda Ardern thanked Jools for all she did for the country.
“You can’t really describe an icon, but you can thank them. Rest in peace and love, Dame Jools Topp. With so much gratitude for all you did for Aotearoa, New Zealand. Xx,” Ardern said on social media.
Journalist and broadcaster Miriama Kamo said: “I’m heartbroken about Jools’ passing. She and her beautiful twinnie Lynda have been the soundtrack of my life, of the lives of so many [New Zealanders].
“Not just entertainers but allies, fighters, stalwarts for what’s right, what matters. Today our hearts break, even as we sing Jools’ song.”
