It was raining when Auckland truck driver Daniel William Raukawa Taukava, 41, was speeding along State Highway 1 at Atiamuri near Taupō.
He wasn't wearing a seatbelt, hadn't had enough sleep over previous days, and three months earlier had deliberately disabled the truck's electronic braking system.
On the evening of January 25, 2017, as Taukava approached a right-hand bend in the road, the truck, which carried a 90km/h speed limit, crossed the centre line and collided with a motorcyclist killing him.
The truck drove into a culvert and back onto the road, swerving between north and southbound lanes and colliding with and sliding along an embankment, coming to rest in a jack-knife position.
Nineteen months after Napier motorcyclist Te Wanehi Wakefield, 56, lost his life in the crash, Taukava has been jailed for two years and 10 months for manslaughter, and disqualified from driving for four months from the day of release.
