Mr Deane was admitted after the accident last Thursday, and family members flew in from England to be at his bedside.
"I would like to offer the condolences of the Waikato Police to his family and assure them this matter is being dealt with in a thorough and professional manner," Mr Bu Bear said.
The Waikato University student lives at Brookfield Accommodation in Hillcrest, across the road from where the accident happened.
His Twitter account says: "Retired from capitalist pursuits to study philosophy & psychology, it's chasing my bliss, are you chasing yours?"
The driver of the car, 62, has been arrested and will appear in Hamilton District Court tomorrow charged with failing to stop or ascertain injury. Police would not rule out further charges but refused to comment further.
