Police investigating the disappearance of a millionaire more than 20 years ago have examined previously unsearched areas of Akaroa on the Banks Peninsula.
Graham Vanstone vanished from his hillside home in Akaroa on September 5, 1999, and has not been seen or heard from since.
His disappearance at the age of 49 was out of character, and he was a much-loved family member and well-respected member of the community.
Two years ago police launched a fresh probe, a third review of the case, after a coroner determined his death was "unascertained".
On Thursday and Friday morning search and rescue officers took their investigation to an area of Akaroa that had not been previously examined, a police spokesperson said.

"Police have followed a number of lines of inquiry since Mr Vanstone's disappearance but his whereabouts remains unknown.
"Police encourage anyone to come forward with information, even if you have previously spoken to police, to help Mr Vanstone's family get the closure and resolution they deserve.
"We know there are still people who can help us finally solve this case."
The spokesperson said police were hoping that given the time that had passed, those people might now feel in a position to come forward and help.
