The Topp Twins make their first public appearance together since cancer diagnosis

Beloved Kiwi entertainers Lynda and Jools Topp have made their first public appearance together since their cancer diagnosis.

Stepping out together, the siblings were honoured at The Topp Twins' 40th Anniversary Tribute Concert at Auckland's Civic Theatre on Monday night.

The tribute concert saw artists including Tami Neilson, Anika Moa, Ria Hall, Jackie Clarke, Annie Crummer and Don McGlashan perform, while some of New Zealand's top comedians and special guests also pay homage to the godmothers of the local comedy scene.

Taking to Facebook following the event, the Topp Twins shared some behind-the-scenes shots from the show, as well as a family photo.

"Wow what an amazing night. Topp Class performers, crew and audience, it was the best night ever. Thank you Lynda and Jools Topp," the post said.

During the event, the twins said they are "good fighters" and are vowing to carry on their battle against breast cancer.

"It's been a tough year for Linda and me, both having cancer," said Dame Jools Topp.

"It's not over yet, there's still lots of treatment to happen and all that sort of stuff. But we're good fighters, we've got a lot of vouchers saved up because we've made a lot of people laugh."

It comes after the Topp Twins revealed in March that they were both fighting breast cancer.

The pair became Kiwi television staples with their show The Topp Twins, where they played characters Camp Mother, Camp Leader, Ken and Ken.

Proceeds from the concert will help pay for the twins' ongoing treatment and living costs.
