The 23-year-old who grew up on Auckland's Hibiscus Coast, has just returned from a year modelling the US.
While Stateside, Cassidy hung out with Kylie Jenner and then boyfriend Tyga, with Kylie seen mimicking Cassidy's Kiwi accent on Snapchat.
Now back home in Aotearoa, Cassidy was chosen out of eight finalists in Bravo's search for a local host.
Cassidy's vibrant on-screen presence secured her the role, Bravo said.
"Becoming Bravo's first-ever local host is going to be the most incredible adventure and I'm thrilled to have the opportunity to bring a New Zealand perspective to the brand. I can't wait to accept the challenge and get started!" said Cassidy.
She will start in the role immediately, beginning with a first assignment interviewing the stars on the red carpet at Thursday night's New Zealand Music Awards.
Cassidy will then feature in Bravo's on-air summer campaign and report on New Zealand's major summer events, before preparing for her regular celebrity and entertainment news updates, set to launch early next year.
