Drugs are believed to have been involved in an incident at a Raglan beach car park that left one person dead and another hospitalised.
Fire and Emergency NZ shift manager Scott Osmond said the death had been classified as a medical event, while a police spokeswoman said it would be investigated by the coroner.
However, a second person in the car was taken to Waikato Hospital in a moderate condition, she said.
The Herald has learned that drugs were believed to have played a part in the death, which was understood to be accidental.
Emergency services were called to the incident at Manu Bay about 3.30pm yesterday.
