Cassie Henderson.

Cassie Henderson is New Zealand's chart-dominating pop storyteller, turning heartbreak into history-making hits. Her breakthrough single "Whatever" (2023) held #1 on NZ airplay for 12 consecutive weeks – the first female Kiwi artist to achieve that since Lorde in 2017. She then shattered her own record with "Seconds To Midnight (11:59)," commanding the top spot for 15 weeks and earning her Best Pop Artist at the 2025 Aotearoa Music Awards.

Henderson's "Chronicles of a Heart Broken" trilogy maps the emotional wreckage of lost love across three sonically distinct EPs. The Pink Chapter introduced her confessional style, while The Yellow Chapter leaned into pop-punk bravado, showcasing a voice that shifts from vulnerable to commanding. The Blue Chapter drops early 2026.

On stage, Henderson transforms intimate venues into experiences – she's headlined nationwide tours, sold out Christchurch's James Hay Theatre, and opened for international acts including Alex Warren and Lauren Spencer Smith across New Zealand and Australia. Festival crowds at Rhythm & Vines, Rhythm & Alps, and Homegrown have witnessed her rare ability to command a crowd through feeling rather than flash.

Her 2025 appearance on The Voice Australia brought in new fans globally, with her viral blind audition introducing her powerhouse voice to the world. "There is nothing else I want to do in this world," Henderson declared – a statement of passion that resonated far beyond the TV studio.
