The motorcyclist killed in a crash in Cromwell early this morning was 37-year-old local man Scott Alexander Mackenzie.
Police have finished the examination of the crash scene, reopening Shortcut Rd around 2pm.
"We have spoken to the family and with a number of persons living near the crash site," said Senior Sergeant Ian Kerrisk.
"That, along with the scene examination means we now have a much clearer picture of what occurred."
Nearby residents had heard a motorcycle travelling around the area about 4 this morning, with the noise stopping suddenly shortly after.
