Police have been alerted.
A family member, Jack Nambari, posted the missing report on Facebook and voiced the fear that the boy, David Manihave, may have been snatched by a passerby.
He was last seen wearing a white collared shirt with a square design below the breast pocket and brown shorts and shoes, possibly black.
His parents are from the New Guinea Islands region.
David went missing from the BSP ATM area at Vision city at about midday yesterday.
