A person died following a crash involving a motorcycle and a vehicle on State Highway 4, south of Oruakukuru Rd, near Raetihi. The incident happened around 10am on Sunday.
Meanwhile emergency services were called to a single-vehicle crash on Kaitaia-Awaroa Road in Herekino shortly after 1am.
A police spokesperson said one person died at the scene.
"Three other people were taken to hospital with serious injuries," they said.
The road has reopened after being examined by the Serious Crash Unit. The cause of the crash is being investigated.
This follows a single-vehicle crash on State Highway 23, just south of Raglan.
The crash was reported to police shortly after 11.30pm and the single occupant of the vehicle died at the scene.
"An investigation into the cause of the crash is underway," police said.
These deaths follow three earlier fatalities on the roads and a tragic start to the Anzac Day long weekend.
The road toll includes the deaths of two motorbike riders and a motorist in the south of the North Island yesterday, as well as the four people who died in a horror crash in Invercargill on Friday afternoon.
After 6.30am yesterday a person died in a crash on Arapaepae Rd (State Highway 57) in Levin, south of Palmerston North.
Two others were injured, including one critically, in the same incident.
Then a crash between a motorcycle and another vehicle took place in Whāngārei at the intersection of Western Hills Drive and Douglas St at 9.30am.
Later in the evening, around 5.30pm, there was another motorbike crash in Awakeri, just outside of Whakatane in the Bay of Plenty.

On Friday four teenagers died in a shocking crash in Invercargill after the Ford Ranger they were travelling in collided with a concrete truck on Queens Drive.
Three of the boys were 16 years old and one was 17 years old and they all died at the scene. The truck driver suffered minor injuries.
Three of the young men were from the seaside town of Bluff, south of Invercargill, and it "was a tragedy for the Bluff community as a whole", Southland area commander Mike Bowman said.
It was a small town and the deaths would have a "huge impact".
"Obviously, it's a tragedy for the families of the four deceased young men," Bowman said today, his voice shaking.
"And we will be working very closely with them."
