Officer Six described the pursuit and shooting during an emotional testimony: "I prepared and pulled up about 15m from the back of his vehicle. A patrol vehicle flew past me on the right and was only about 2m from Mr Kelly-Tumarae's car. I thought 'what are they doing'."
"[Mr Kelly-Tumarae] looked like he meant business and wanted to kill whoever was in the vehicle," Officer Six said.
"I'm going to see brains coming out the other side of the vehicle," the officer recalled thinking as Mr Kelly-Tumarae pointed the weapon at fellow police. "He looked down the barrel in a slow and calculated aim."
Officer Six, who is known to be an experienced officer, stepped out of the patrol car and shouted "armed police" before Mr Kelly-Tumarae turned to face him.
"The barrel was pointed in my direction and I thought he was going to shoot me."
Believing Mr Kelly-Tumarae was about to shoot, Officer Six fired "four to five" rounds at his target. "I thought, 'He's still standing and still facing me. I haven't hit him'."
The officer fired another five or so shots before Mr Kelly-Tumarae ran towards the cemetery, dropped his gun and collapsed.
"I wanted to dominate him, I wanted to be aggressive and wanted to go home that night," Officer Six said when justifying his actions. He said he felt his job was to protect the two officers.
The coroner's report called for police to review training protocol in relation to the verbal warning issued by armed police officers to armed offenders.
He was also critical of Officer Six, who shot Mr Kelly-Tumarae, referencing the Independent Police Conduct Authority report, which found he acted "on instinct rather than training".
He recommend that police review their training protocol in relation to the warning issued by armed officers to armed offenders.
Despite this, the coroner said the "causative factor" in the teenager's death was Mr Kelly-Tumarae's action in presenting and brandishing a firearm.".
Mr Kelly-Tumarae's grandmother, Narina Tumarae, told Hawke's Bay Today after the inquest that the truth remained hidden. "I question a lot of what they have to say. They wasted his life and a lot of it doesn't add up."
