Lance Kaiki was located near a cycling track and Detective Sergeant Nick Pritchard, of the Hutt Valley Police, said it looked as though he had crashed.
However, it would be over to the coroner to establish the cause of death.
Kaiki, 43, was last seen around 2.20pm on Thursday when he was going for a ride in the park.
Police began searching for him yesterday. It was actually family members who found him today.
