this morning that police were still searching for Mohi.
"We have no updates overnight but we are continuing to work closely with John's family and a number of police staff are working to locate him," Owen said.
"We also have Land SAR and local volunteers combing the Maketu area. The search will reconvene at 8am this morning."
Mohi, who has dementia, was last seen on Wilson Rd North in Maketū.
A police Eagle helicopter helped with the search on Tuesday night and on Wednesday 56 searchers split into teams of eight to carry out a grid search around his home in the 30C heat.
Mohi's granddaughter Ronnie Tapsell-Walters, 37, said Mohi took a one or two-hour strolls every day around midday and believed he may have become "confused and disoriented".
She and other whanau remained hopeful of a good outcome.
"My grandfather suffers from outset dementia and a bipolar condition but otherwise he's physically fit and as part of his daily routine is a stroll around his neighbourhood.
Tapsell-Walters said the disappearance was out of character and she called the police after he did not return within two or three hours.
"We believe he is alive and will be found, it's just a matter of time.
"He might just need a ride home, to be honest."
