Police have mounted a large-scale search for a man missing from a nursing home on Sydney's north shore.

Raymond Spackman, 73, was last seen at 2pm on Friday, when he walked away from the aged care home, on Greenwich Road in Greenwich.

Police said Mr Spackman is of caucasian appearance, with a stocky build.

He was last seen wearing a long-sleeve shirt, grey tracksuit pants, a blue cap and reading glasses.

Residents in Greenwich, Wollstonecraft, Waverton and surrounding suburbs reported hearing the police helicopter PolAir hovering above the suburbs and broadcasting a message at around 8.30pm on Friday.

An announcement on loudspeaker advised residents that police were searching for the 73-year-old.

Residents also reported hearing sirens in the area.

Local police, the dog squad and officers from the Marine Area Command are part of the search.

The police helicopter appeared to focus on local parks and reserves as it circled the surrounds of the nursing home.

Anyone who sees Mr Spackman is asked to call police immediately.
