Police say the circumstances surrounding the death of a man in Rotorua remain unclear.

The man's body was found in a stream in Fordlands yesterday.

A post mortem examination has been completed - but police say while they have a provisional cause of death - more work needs to be done.

They say it's still too soon to speculate as to whether the man’s death is suspicious or not.

At this stage it's being treated as an unexplained death.
