Support continues for first responders who attended the head on crash south of Picton.

Seven people were killed in a collision between a van and a truck on State Highway 1 on Sunday morning  - two others from the van have serious and critical injuries.

The Pukekohe family was on their way home after attending a funeral in Dunedin.

St John Wellbeing Manager Adele Saunders told Tim Dower first responders are resilient but human emotion always comes through.

She says every crash scene emergency staff go to has a different effect on people.
