"This was a completely preventable crash, which has sadly claimed the life of a young man" said Senior Sergeant Ian Kerrisk of the Alexandra Police.
"We have a local family grieving the loss of their son and brother, and our community feeling the loss of one of our local boys from a well-known family.
"We can only hope that this tragedy helps reinforce the message about the need to keep ourselves our friends and our whanau safe."
Speed and alcohol were significant factors in the investigation, he said.
