Police have searched two properties in the hunt for an Auckland man who disappeared 31 days ago, as a detective says "our fears for the worst continue to grow".
Sandringham man Ronny Okeke, 60, was last seen on April 27 at a New World supermarket in Mt Roskill. He was reported missing five days later.
Authorities are urging members of the public to come forward with information.
Detective Inspector Glenn Baldwin said the investigation team was still trying to piece together Okeke's movements.
"In the past week, two search warrants have been executed at two Auckland properties as part of our ongoing inquiries," he said this afternoon.
"The longer we do not hear from Ronny our fears for the worst continue to grow.
"Ronny is a husband and a father, and his family deserve answers as to what has happened to him."

Baldwin reiterated that the man's family lived overseas.
Okeke has not been heard from since April 27.
His last confirmed sighting was on surveillance camera footage as he left the Stoddard Rd New World at about 4.42pm, according to police.
He attempted to call his wife, who lived overseas, at around 11am on the same day but did not pick up when she tried to call him back.
Police urged anyone with information about the missing man to call 105.
