A police chase that ended in a fatal crash outside Oamaru should have been abandoned earlier, the independent police watchdog says.
Luke Bradley Savigny (25) was jailed for five years seven months earlier this month before the High Court at Dunedin after pleading guilty to the manslaughter of 32-year-old Christopher "Chipper" Narayan Blair.
Savigny was drinking and using methamphetamine and cannabis before driving north from Dunedin on March 21 last year.
Police received multiple complaints from members of the public as the defendant drove erratically, crossing the centre line and exceeding the speed limit on numerous stretches of State Highway 1.
