Two people have died after their car left the road and plunged into Lake Rotoma, near Rotorua.

Police divers this morning retrieved the pair's bodies as their silver, four-door vehicle was removed from the lake.

Emergency services had been called to the scene at 12:40pm yesterday after the car left State Highway 30, east of Rotorua.

"Two people were recovered deceased from the lake by the dive squad," police said today in a statement. "Police are working to support the family of those who have died."

A Lake Rotoma resident said the corner was notorious for crashes.

Shane, who would only be known by his first name, said he used to live across the road from the corner for about four years before moving down the road a few years ago.

In that time there were often people losing control of their cars on that corner, he said. "I"ve seen a few accidents but nothing where they've gone right in."

Shane said there had been a metal safety barrier recently installed.

"Since that happened, we haven't had many crashes - until now. It's pretty unreal."

Shane and his son-in-law had been travelling from his home to visit his daughter, who also lives at the lake, within minutes of the crash, he said.

"We had actually driven past the crash site just 10 minutes before we heard the sirens."

Shane spoke to the Rotorua Daily Post while watching the car wreck be pulled from the water.

He said the corner has a layby where people diving or swimming often park their cars.

"It would've probably saved their lives, if there were cars parked there."

Lake Rotoma is the fourth largest lake of the 11 lakes in the Rotorua Lakes district.

Meanwhile, police have confirmed one person is dead after a people mover hurtled down a bank next to SH1 in North Otago this morning.

A police spokeswoman said the single-vehicle crash happened on Main Rd (SH1), Maheno, and police were called at 10.06am.

Police this afternoon confirmed the sole occupant of the vehicle was found dead at the scene.

Police remained at the scene and the investigation into the cause is ongoing.

A reporter at the scene said the van/people mover was about 10m to 15m from the road in a paddock and badly damaged.

There were debris spread across the paddock.

It appeared the car was travelling north when it left the road close to the entrance to Maheno.
