Other people credited Wells for his career, one person calling him "one of the most honest voices in New Zealand writing."
"RIP Peter Wells. Condolences to family and friends. So many amazing works you gave us," another said.
"Peter Wells died this afternoon. He faced his illness with great courage and dignity. Condolences to his friends and especially to Douglas Lloyd-Jenkins," one wrote."
Wells was diagnosed with prostate cancer in November 2017 and began writing on his private Facebook page about them the same month.
The posts traced his journey from diagnosis, through chemotherapy and, most recently in late March 2018, to the point where his oncologist told him his tumours had shrunk by half.
Wells wrote numerous short stories titled Dangerous Desires and he was the author of New Zealand's first gay-themed work published by an openly gay writer.
In 2006, Wells was announced as a member in the New Zealand Order of Merit for his services to literature and film.
