Aged 19 Aizaeah Kori-Lee Tarawa should have been behind the wheel with zero alcohol in his system.
But the teenager was found to be three times over the legal alcohol limit for adults when the car he was driving slammed into an oncoming vehicle killing a young mother and her baby girl.
Judge Greg Davis has released for the first time an agreed police summary of facts after Tarawa appeared in the Whangārei District Court last week.
The summary revealed Tarawa had two previous convictions for driving with an excess breath alcohol level. He was convicted in Kaitaia District Court on January 18, 2018, on two charges of driving with an excess breath alcohol after being arrested in August 2017, then again in September, 2017.
Fourteen months after those convictions Tarawa was driving a silver sedan that collided head-on with a northbound people mover on State Highway 1 near Oruawharo Rd in Topuni, on March 30 this year.
