The Honda then spun into another vehicle behind Mr Sparrow's, which was being driven by Mr Sparrow's wife, resulting in a "T-bone" crash which killed Mr Lawrence-Samuels and Mr Wikaira instantly.
There had been light rain, it was dark, and there were no road lights.
Alongside these conditions, Mr Shortland said it was possible the road conditions had contributed to the crash. In the two weeks prior to the incident, two other crashes occurred in the same area, although they did not result in deaths.
The police could not be certain what speed the Honda was travelling at, only that it was in excess of 100km/h.
The Honda was "for all intents and purposes in a warrantable state of fitness", a VTNZ vehicle inspector had said.
Before the incident the pair who died, plus a third occupant, Rehurangi Tauroa, who survived, had been training for rugby, and had then consumed beer and a marijuana joint at the Kaeo Rugby club.
After this the young men decided to go to Kerikeri for something to eat, once a party they had planned to go to fell through. But they never made it.
"It is a tragic and unnecessary death," said Mr Shortland.
"It is most fortunate that no one else was killed or seriously injured in the crash. Particularly Mrs Sparrow and Mr Rehurangi Tauroa."
