Sellers became one of this country's most famous broadcasters during a 34-year career for Radio New Zealand.
Sports commentator Keith Quinn said Sellers died in a rest home in Dunedin last night.
Quinn, a long-term friend and fellow broadcaster, says Sellers never married and was an only child so had no family.
He says he had a wide circle of friends but has outlived most of them, apart from a small group of mainly sports broadcasters.

Quinn says Peter Sellers was a unique and wonderful character and a tremendous influence on fledgling broadcasters.
Sellers interviewed many famous identities in his career, including Olympic gold medalist Mark Spitz, Australian and English cricketers Don Bradman and Fred Trueman, and Springboks coach Danie Craven.
He was known for his encyclopedic knowledge of all sports and colourful tongue.
In 1956, when swearing on air was a big no-no, he infamously blurted out on radio: "Bloody hell that's a lot of pies!"
