A person has died and three others have been injured after two separate crashes overnight.
The fatal crash happened in Matamata about 4.40am.
One car was involved. The driver died at the scene. No one else was in the car when it hit a wall on Smith St.
Police are yet to release more details about the person who was killed and won't until next of kin are notified.
Three people were also hurt in another single-car crash in Whangarei.
The car reportedly caught fire after the crash, but emergency services managed to get the occupants out.
Emergency services were called to the scene on Whangarei-Dargaville Highway about 1.50am.
All three injured people were taken to Northland Base Hospital - two in a serious condition and one in a moderate condition.
The Matamata crash was the second fatal incident on New Zealand roads in two days.
Haydn David Clark, 20, from Drury, Jocelyn (Anne) Fielder, 64, and her husband Ian Fielder, 66, were killed in a smash near the Kopu Bridge in the Coromandel on Thursday night.
Clark's father, 54-year-old Jim Clark, the sole survivor, was cut from the wreck and taken to Middlemore Hospital in a critical condition. He remains in hospital.
Police say Haydn Clark was driving a stolen ute which crossed the centre line and collided with the Fielders' car.
He was facing methamphetamine charges and was on bail, including a 24-hour curfew order.
The Fielders' neighbour said the couple had been on their way home from a friend's place, where they had dinner every Thursday, when the crash happened last night.
"It was a little ritual they had," he said.
The neighbour said he was heartbroken at the deaths of the couple, who he described as "fun-loving, friendly" people.
"I couldn't believe it. I still can't believe it.
"It's just wrong."
The 19-year-old disappeared without her wallet or mobile phone.
