The neuropsychologist's death was announced by MAFS' John Aiken, who took to Instagram to pay tribute to his former co-star while sharing some treasured memories.
"I’m heartbroken and devastated that my friend and dear colleague Trisha has passed away. We shared an amazing seven seasons of @MAFS together," John wrote.
"She loved everything New Zealand, relationships, the All Blacks, the Black Caps, French wine and travelling the world. I’ll miss you, Tish. Thank you for all the memories. Jx," he ended the post with.
Trisha, who left MAFS in 2020, spoke to Woman's Day in 2021 about her decision to leave the hit show.
"By the end, I couldn't compromise my professional and personal standards because there were participants on the show who I felt shouldn't have been there," she said.
"At a couple of dinner parties I felt sick. I felt in my guts that this wasn't what I'd want to be watching at home on TV. The participants we got in season six and seven were so outrageous and outside the norm that it wasn't what I signed up for."
New Zealand-born Trisha had moved back to her home country after lockdown in 2020, to be with her partner Roger who she met through friends in 2018.
"Lockdown was a nice time to reflect and it reinforced that I'd made the right choices in my life with leaving MAFS and coming back home," she said in her Woman's Day interview.
Trisha is survived by her daughter, Gina, and her partner Roger.
A Nine spokesperson said that the network was deeply saddened to hear the news of Stratford’s death.
“Our sincerest condolences and heartfelt sympathies go out to her family and those closest during this difficult time.”
