The defence said Ms Manuel had stepped out on the road and collided with the vehicle. Fungavaka had struck her the second time because he had not seen her as she lay on the poorly-lit road.
Members of Ms Manuel's family, including her daughter, parents and sister, told the court of their deep sense of loss and pain. Fungavaka had shown no remorse and had forced the family to endure a trial.
Ms Manuel's sister, Saffron Bates, said Fungavaka had preyed on her sister, and the relationship had been disastrous.
"He has shown no remorse. He has taken every step to avoid responsibility (for) my sister's death," she said, describing him as sadistic.
"She was loyal, loving and caring, and a person who had a few imperfections, but who doesn't?" she added.
"A decision was made by you, and you did murder my daughter. You should get life for what you did," the victim's mother Marie Manuel said.
Justice Faire said an unremorseful Fungavaka had deliberately targeted Ms Manuel, while Crown prosecutor Bernadette O'Connor said medical, scientific and eyewitness evidence had all come together to establish that both impacts were deliberate, and performed with murderous intent and a high level of "brutality and callousness."
Counsel Kahungunu Barron-Afeaki said his client had expressed remorse in a police interview, and maintained that he had not seen Ms Manuel. Not a day went by when his client did not feel pain or anguish for what had happened.
