Rangitoto College principal Patrick Gale said the school acknowledged Cederwall's death "with deep regret".
"Robbie was an outstanding young man who fully immersed himself in all facets of school life."
As a leader he contributed greatly to the culture of the school through his involvement in performing arts and in the Māori and Pasifika group, he said.
"Robbie was a popular and cheerful student who had a positive impact on many people's lives; he will be sorely missed by his friends and teachers at Rangitoto College.
"Our deepest sympathies and thoughts are with his family and friends at this time of grief."
An 18-year-old has been charged with dangerous driving causing injury and is due to appear in the North Shore District Court on Thursday.
The police investigation is ongoing and the death has been referred to the coroner.
Police previously said a number of people were in the vehicle and on the tray.
The ute was reportedly doing "doughnuts" on the beach before it rolled.
The vehicle was then righted and the driver fled.
Police arrived to find seven people still on the beach.
Cederwall was flown to Auckland Hospital and the others were taken to North Shore Hospital.
The driver then returned.
Waitematā East Area Commander Inspector Sundip Patel previously told the Herald alcohol was a factor.
