The impact saw both vehicles end up in the grass on different sides of the road.
Gurnick successfully requested the relaxing of a bail condition not to associate with the victim's mother whom he said he had previously seen on a regular basis as the victim was his "best friend".
Gurnick told Judge Jonathan Down it had taken police 18 months to lay charges, the most serious of which has a maximum penalty of 10 years jail or a $20,000 fine.
The man first appeared in court in June.
After the Herald clarified an interim suppression order, the crown advised it was put in place to protect the surviving victim, while Gurnick advised he would continue to seek it until sentencing, when it would not be pursued.
Judge Down agreed to keep suppression in place until the end of the year.
The matter would now be referred to restorative justice.
Judge Down convicted the man on the two charges and remanded him on further bail for sentencing in December.
