Police say they will not be releasing the findings of the post-mortem examination completed on the man found dead beside viable and potentially deadly pipe bombs near Auckland鈥檚 Southern Motorway.
It has since been confirmed that the devices found have been destroyed while police hand over the man鈥檚 body to the coroner.
Counties Manukau CIB Detective Senior Sergeant Mike Hayward said the post-mortem indicated the man died from self-inflicted injuries.
He said they were not treating his death or the bombs as a criminal matter, and the examination of the scene in Highbrook was completed yesterday.

鈥淧olice are currently unable to release further details surrounding the man, as formal identification procedures are yet to be completed.
鈥淣ext of kin have been contacted and police are currently supporting them through the next steps in the process.鈥
The man鈥檚 body was discovered about 11.30am on Tuesday, leading to the complete closure of the southbound lanes and long delays to traffic.
Hayward said staff 鈥渃arefully balanced public safety considerations as well as the integrity of a scene鈥 yesterday when they shut down large sections of the motorway, jamming traffic for hours.
鈥淕iven the scene鈥檚 proximity to a major state highway, it was imperative that the area was made safe before proceeding.鈥
Hayward said there was no longer a risk to the wider public.
He confirmed yesterday that the pipe bombs were 鈥渧iable鈥 and capable of causing death and serious harm.
鈥淭hanks to specialist assistance at the scene, these devices were safely removed and have since been destroyed.鈥
The Southern Motorway reopened on Tuesday after the sudden closure of the southbound lanes of SH1 between Princes St East and Highbrook Drive in Highbrook at lunchtime.
Just before 3pm, all lanes on SH1 reopened.
Traffic built on the southbound lanes of the Southwestern Motorway as motorists avoided the closure.
