Auckland-based Chance was a "busy entrepreneur with quite a few businesses" and had been described to police as being "extremely positive, happy and upbeat".
He was always happy and into his health and fitness.
His mother and two sisters, said to be living in the United States and Australia and working with police to find him, are "extremely concerned and becoming more and more distressed by the day".

Chance's family said his disappearance was out-of-character and police do not know where he was heading. The last sighting was captured on a CCTV camera on the motorway at 4.17pm.
"From what we know of Denver it is very out of character for him to disappear and have no contact with his friends or family," Detective Senior Sergeant Megan Goldie said this afternoon.
Police say he is 178cm, has dark brown hair and a tattoo which runs up his arm to his shoulder. He wears an Oakley watch and was last seen in shorts and a singlet.
Police urge anyone with information to contact North Shore police on 09 477 5000 or Crimestoppers on 0800 555 111.
