A post mortem in Auckland answered some of the questions arising from the discovery of a man's body in the Awanui River, beneath the bridge in Allen Bell Drive, on Tuesday afternoon.
The body was discovered by children shortly after 1pm, the officer in charge of the investigation, acting Detective Senior Sergeant Mark Dalzell, saying police believed they knew his identity, but had yet to complete the formal identification process. Next of kin had been informed, however.
The deceased was later named as 35-year-old Kaitaia man Aaron Mark Roycroft.
Mr Dalzell said on Tuesday, and again yesterday, that the death was being investigated as "unexplained." He was unable to say there was no possibility of foul play, but was increasingly doubtful that there was.
Once the post mortem results were received he stated that there were no suspicious circumstances, and Mr Roycroft's death had been referred to the coroner.
