Earlier, volunteer firefighter Michael Sparrow, who helped the race organisers and was the first to attend to Samantha after the crash, said it seemed "hours and hours and hours" before an ambulance arrived 10 minutes after being called and Samantha Body-Mouat was put on to a stretcher.
Samantha's mother Lisa Strydom, grandfather Les Bloxham and uncle Emerson Weston were among those who questioned witnesses.
Mr Weston read a statement from Wendy Clark, a registered nurse in the accident and emergency department at Tauranga Hospital, who was at the race that Samantha crashed in.
Ms Clark's husband had asked bystanders if there was anyone with medical expertise in the crowd and someone replied "no".
Ms Clark said she suggested to an unidentified person at the crash scene that Samantha should be removed from the car so she could be treated but her suggestion was declined.
"I watched her bleed to death basically," Ms Clark said in her statement.
Ms Clark was horrified that Samantha's helmet and neck brace were removed - an action that went against all medical protocol.
It showed that those who handled the emergency situation before a St John Ambulance arrived had no knowledge of the human anatomy, she said.
Debbie Beadle, who was secretary of Kaikohe Speedway at the time of the crash, said St John paramedics had been booked for the day and checks were made as to their availability five times before the event.
However, she said, an administrative change by St John that required bookings to be made from Auckland was not notified to race organisers.
Anthony Taylor, one of the organisers, said all drivers were informed a day before the races that there would not be any ambulance on site - something that was disputed by Ms Strydom.
Ms Strydom said people went into a panic after her daughter's crash and everything was a "shambles".
Ms Strydom said she'd have to live with the fact that there was no ambulance, first aid kit, neck brace or breathing tube on site.
Her family also questioned Mr Taylor's decision to remove Samantha's vehicle after the crash and strongly disputed his observation that it had a "frayed accelerator".
Mr Taylor said the vehicle was removed after the organisers were told by police and the Department of Labour that there was no reason for them to impound it.
The inquest continues today.
