Police have released chilling CCTV footage of Orewa man Mike McClennan on the day he went missing.
McClennan, the 75-year-old father of former Warriors coach Brian McClennan, went missing from Hatfield Beach, Orewa at about 5pm on Wednesday last week.
While Search and Rescue teams have scoured the area for the man, who suffers from dementia and was last seen walking along the Hibiscus Coast Highway, McClennan is yet to be found.
Police have now released CCTV footage of McClennan walking north along the highway on the day he went missing. He was wearing a red and black jacket. Police say he was also sighted with the jacket off and wearing a black t-shirt.
"We are once again asking our community to send this message far and wide as we need to know if someone has picked Mr McClennan up and driven him to a different location," said senior sergeant Brett Henshaw from the Waitemata north police.
"This could have been a tourist, so it is imperative that our community help us get this message out there."
Snr Sgt Henshaw thanked members of the public who have already given up their time to help with the search. He asked that people continue to look in their sheds and properties in case McClennan has sought shelter.
Anyone with information can ring the police 105 number.
Last week, Brian pleaded with the public to help find his missing father.
"We really need to know where he is, we're really worried about his safety and his health," said Brian.
"He wanted to go home, and I tried to tell him just hang on, please," said Mike's wife, Maureen.
He was being cared for in Orewa's Milton Court Rest Home but went missing on Wednesday afternoon.
"He can't be out for a long time; he's suffering anxiety as well. He's four times past the pills he should have had," Maureen continued.
