Police believe the body of a man found in the Waikato River belongs to a 45-year-old Hamilton man who went missing last week.
They have confirmed that the body is not that of missing Kawhia man Trevor Smith.
Police said the 45-year-old man went missing last Wednesday and they are appealing to the public for sightings of him near the Waikato River or any bridges on March 19.
Police were notified of his disappearance last Friday. The man was wearing a dark hooded sweatshirt, dark pants, white sneakers and a red and black bag on his back.
The man will be named once he is formally identified, police said.
Hamilton Detective Senior Sergeant Ross Patterson said the body was located by water-skiers in the Waikato River south of the Horotiu Bridge shortly after 9am yesterday.
"Though the formal identification of his body is not expected to be completed until after a post-mortem examination in Auckland today, Police are satisfied the body is not that of missing 70-year-old Kawhia man, Trevor Smith."
Mr Patterson said while the nature of the man's death remains unexplained, his death will continue to be treated as unexplained until such time as information comes to hand on how he died.
