"As the defendant drove along this stretch of road he did not identify the presence of the male in time to avoid running into him," the summary said.
"The defendant swerved to the left to avoid hitting Mr Jack but he felt his front and rear tyres run over him."
Manley continued home and made no attempt to stop and establish what he had hit or whether any injuries had been caused.
A few minutes later another car drove along Te Ngae Rd and struck Jack. Emergency services were called but he was found dead at the scene.
Manley handed himself into the Rotorua police station two days after the incident after seeing media reports.
"In explanation he stated, 'I thought it was a dog or an object. I just wanted to get home'," police stated.
"Now I realise I should have stopped. It was just black and I couldn't see anything."
Police have not been able to establish how Israel Jack came to be on the road in the first place.
He was found with multiple injuries which were caused by being struck by the cars.
"It could not be determined whether either of the two vehicle collisions caused the male's death."
A pre-sentence report was ordered and Manley will re-appear in court for sentencing on April 1.
Restorative justice was declined by Mr Jack's family.
