North Shore police are searching for Stephen Kapeli, who has been missing for three days.
They said Mr Kapeli, 26, was last seen in Takapuna on Wednesday.
Detective Sergeant Steve Brewer said Mr Kapeli's disappearance was out of character, and his bank account and cell phone have not been used.
Mr Kapeli was known, however, to spend hours at the North Shore beaches or Lake Pupuke, Mr Brewer said.
Any sightings of Mr Kapeli - 1.79m tall, of medium to solid build and last seen wearing shorts and a t-shirt - should be reported to the police.
