Inverarity had suffered moderate injuries but his passengers, aged 17 and 18 at the time, had to be cut from the wreckage. They were flown to Whangarei Hospital with serious injuries.
The sentencing was delayed because Inverarity, through his lawyer Doug Blaikie, had disputed aspects of the police summary of facts. One of those was whether it was possible to exactly determine his speed before the crash, the other whether one of his passengers had suffered a broken back.
On the question of the broken back, Judge Keith de Ridder said the term described a range of injuries. While there was no suggestion the victim would be permanently incapacitated by her injury, it was nonetheless "very significant" and involved compressed and cracked vertebrae.
Both victims had suffered a broken leg, one requiring a rod to be inserted to help it heal.
Judge de Ridder said both appeared to have made a full recovery in terms of day-to-day functioning but had suffered a lot of pain and spent a long time in hospital. They would live with the effects for a long time.
An aggravating feature was Inverarity had refused a request by one of his passengers to slow down. Members of the public had tried to warn him of the initial crash but he was travelling so fast he did not see them. His "extremely dangerous" speed, although over a relatively short period, was another aggravating feature. Speed was the only reason he failed to stop in time.
Taking into account Inverarity's remorse and acceptance of responsibility, Judge de Ridder sentenced him to eight months' home detention and disqualified from driving for two years. He was ordered to pay emotional harm reparation of $650 to one victim and $850 to the other.
