The man who died on Auckland's southern motorway yesterday was a client of Framework Services, a company providing mental health services in Auckland.
The man fell from a vehicle, owned by Framework Services, which was travelling at a high speed on the motorway next to the Ellerslie train station.
There were other clients in the van at the time of the incident, though it is understood that there are no suspicious circumstances.
One director of Framework Services said he was shocked and described it as "really sad".
Another director said he was "very deeply saddened" and the staff were affected.
He said there was no indication at all that the man was agitated or at risk, but he did have a history of mental illness and it was an impulsive action.
He confirmed the only staff member in the white Hyundai van was the driver of the vehicle, and the deceased man had been riding in the back with other clients.
The incident caused major traffic problems on the motorway and in the area for hours.
St John ambulance treated a second person at the scene. It is understood he was another client of Framework Services and was in shock at what happened.
The police Serious Crash Unit is still investigating.
