A serious crash involving a motorcyclist and a truck temporarily closed the Southern Motorway heading northbound past Papakura.
The crash scene has now been cleared but motorists should expect significant delays heading north and southbound.
A police spokesperson said they were in attendance and that the motorway was closed northbound between Karaka and Takanini for a short time.
The New Zealand Transport Agency is reporting that the crash occurred around 3.10pm.
The agency says that a trail of cars is backing up to Drury.
As of 3.35pm both lanes of SH1 were temporarily closed by police.
"The road isn't expected to be closed for a significant amount of time however motorists can expect delays," a police spokesperson said.
The Serious Crash Unit has been advised and the transport agency asks that motorists please avoid the area.
The 19-year-old was found in a remote area in the hills of Upper Hutt.
