The bodies of Jarden, 54 and Ali, 53 were retrieved by police divers yesterday as their silver, four-door vehicle was removed from the lake.
Police extended their sympathies to the families and friends of the pair at this difficult time.
In a statement, a police spokesperson urged anyone who may have seen their vehicle - a silver Mercedes Benz, registration JZY733 in the Rotorua Lakes area on Saturday to contact police.
A Lake Rotomā resident said the corner was notorious for crashes.
Shane, who only gave his first name, said he lived 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."
He said the corner had a layby where people diving or swimming often parked their cars.
"It would've probably saved their lives, if there were cars parked there."
Lake Rotomā is the fourth-largest of the 11 lakes in the Rotorua Lakes district.
