A Rotorua family is asking the community to keep their eyes open for their missing pop.
Trevor Smith, 70, who lives in Kawhia, went missing from Hamilton on Sunday, March 16. Since then up to 50 people a day have been scouring the city's parks, reserves and the Waikato River in the hope he will be found.
Peter Low, who is stepfather to Mr Smith's grandchildren, said he was hoping to jog Rotorua residents' memories, especially those who might have visited Hamilton in the past two weeks.
"The grandkids and my wife are emotionally and physically drained," Mr Low said.
"We've been through every reserve, park, under all the undergrowth. It's a mystery where he's got to. We've no clue.
