Police yesterday named the three people who were killed - Susanna Stewart, 48, from Paparoa, Sadie Stewart, 16, also from Paparoa, and 18-year-old James Wearmouth, of Maungaturoto.

In Pahiatua, near Masterton, career soldier Paul Simpson was left reeling yesterday after learning about the death of an injured driver whose hand he had held in the wreckage of a high-speed crash near Mt Bruce on Sunday.
The driver was retired Mangamaire storekeeper Eric Frank Bird, 77, who died in Wellington Hospital the previous day from injuries he received during the high speed head-on collision on SH2 just before noon Sunday that also claimed the life of the other driver, Rodger Barry James Chappell, 42.
Five people were involved in the crash. Mr Chappell died at the scene after being cut from his car and despite receiving CPR from paramedics.
Corporal Simpson said he stopped when he saw the accident and went to help.
"I went straight to the driver to see how he was and stayed with him. He told me his name was Eric."
The driver of the other damaged vehicle was trapped but conscious, Mr Simpson said, "because I could see his arms moving from where I was". He reassured Mr Bird paramedics were coming.
"We talked about where he was heading and whether he knew what had happened," Mr Simpson said. "I checked him over, and asked him if he could move his feet or feel any tingling or anything like that. I held his hand."
