Police are appealing to the public to help find Denver Chance, who has been missing from Auckland since Sunday.
Mr Chance, 43, was last seen leaving a property in Mairangi Bay, North Shore, about 4pm on Sunday, 24 February.
His family and friends have serious concerns for his safety.
Police said it was very unusual for Mr Chance not to be in contact with his family and close friends.
He is described as 178cm tall and of solid build.
Police are also appealing for sightings of his car, a red 2008 Nissan Skyline, with the registration LGH476.
