It was the second fatal crash on Northland's roads over the long weekend, after a motorcyclist died in a crash with another vehicle in Whangārei on Saturday.
Police have also named a person who died in a crash on Paparore Road, Paparore, on Saturday April 9.
"Police extend our condolences to Mr Taniwha's friends and whānau," a police spokesperson said.
The crash happened at around 11pm on April 9.
Kaitaia deputy fire chief Ross Beddows said at the time it appeared the Isuzu Mu with four occupants had rolled on a corner at the northern end of Paparore Rd and come to rest on its roof.
Taniwha had been thrown from the vehicle and was trapped underneath it.
Three other men, all in their late teens or early 20s, had moderate injuries.
