Stan Walker has warned his fans against "half-truths" surrounding his health issues in a series of videos.
Sharing news about his upcoming documentary on Instagram, Walker, 27, warned fans not to believe everything being said about the singer.
"I've got a documentary coming out, [I'm] excited for everyone to see what's been happening - what's actually been happening, 'cause there's a lot of know-it-alls talking so much s***," he said.
"Just a bit of advice for everybody out there, if it doesn't come from the horse's mouth, then you don't know s***, 'cause even half-truths ain't the truth."
Walker continued: "Other than that whanau, I just want to thank you all for your concerns, your prayers, all that stuff.
Walker's documentary, Stan, is set to screen in March. A trailer released over the weekend showed Walker undergoing various medical procedures.
