Sir Paul Holmes has been admitted to hospital.
A statement released this afternoon by his wife Lady Deborah Holmes and his brother Ken Holmes said Sir Paul Holmes was in a stable condition in Hawke's Bay Hospital.
His family had gathered to be close to him.
Holmes was knighted last week at a specially arranged investiture ceremony.
He has been battling heart problems and the return of prostate cancer, which he said last week was more aggressive than before.
"I don't think Houdini will do it this time. There's a time limitation now - the old cancer found me out and is starting to do some funny things."
Holmes, 62, who ended his broadcasting career in November because of poor health, was a late addition to the New Year honours list, being made a Knight Companion of the New Zealand Order of Merit.
He has been suffering for much of the past year from hypertrophic cardiomyopathy - a genetic heart condition which thickens the muscles and restricts bloodflow - and from prostate cancer.
He underwent four hours of open-heart surgery earlier last year in Auckland Hospital, including nearly a week in an induced coma as he recovered. He was back in hospital in November after he contracted an infection.
"When you have a few health scares it makes you think and it provides an opportunity for perspective," he said at the time, as he stepped down from his role as a mainstay presenter for radio station Newstalk ZB.
He was the station's pioneer breakfast host when it controversially launched its talkback radio format in 1987.
He also headlined TVNZ's flagship Holmes programme until 2004.
