Manu Hausia (28) has pleaded guilty to four charges, including attempted murder at the High Court in Christchurch, New Zealand.

New Zealand Herald reported the harrowing case as it was revealed at the High Court this afternoon, after Hausia admitted his brutal assault committed on September 2.

A Tongan national, who is currently in New Zealand on an interim visitor visa, he pleaded guilty to four charges including attempted murder, injuring with intent and assaulting a child.

He will be sentenced in February 2022.

The summary of facts was read to the court and to Hausia via a Tongan interpreter.

The court heard that the first victim was a solo mum with five children who met Hausia at a rugby game in Auckland at the start of the year. They began a relationship and started living together a short time later in Oamaru. 

At about midnight on June 19, Hausia was at their place in Oamaru waiting for the victim to return home from church.

When she got home, the court heard, he confronted her, requesting to see her phone.

He attacked her. He punched her in the head with full force, causing her to scream and raise her arms up in defence as she lay there, he continued to rain punches down on her head and body, causing her to lose consciousness.

The woman's one-year-old son was 2m from the bed and started crying, distracting Hausia from the assault.

She regained consciousness and crawled into her 11-year-old son's bedroom. He tried to stop the assault on his mother and phoned the police.

Hausia fled the property and was later found in Ashburton.

The victim was admitted to Oamaru hospital, suffering severe swelling to her face, upper body, arms, bleeding from her ears, and concussion.

Second brutal attack

The court then heard at the beginning of August, Hausia returned to Oamaru to live with the victim and her children, in breach of his court bail conditions.

At approximately 3.50am on September 2 after a prolonged drinking session, he became argumentative with the first victim. 

She fought back and began screaming in terror while he repeatedly stabbed her in the back, arms, face, head, shoulders, and upper body.

Hausia used so much force that the scissors broke in half. Emergency services would later find them in her tangled hair.

Her screams woke up her cousin who happened to be staying the night, as well as two children who got up and saw Hausia repeatedly stabbing their mother while she screamed for help, covered in blood.

As the cousin tried to push him away, Hausia turned and lunged at her with either the knife or scissors, stabbing her in the leg and slashing a cut across her face.

When the 11-year-old child also tried to stop the attack, Hausia punched him in the face. The cousin grabbed both children and pulled them into a hallway and shut the door.

Eventually, Hausia stopped his attack and fled, dropping the blood-drenched knife on the lawn.

Both victims were taken to Oamaru Hospital and the first victim was transported to Dunedin Hospital for surgery.

Hausia turned himself in to police about seven hours later.

The first victim suffered horrendous injuries, including nine stab wounds to the back, other stab wounds to the arm, shoulder, face, back of the head, and hand, as well as extensive bruising, significant blood loss, and damage to her saliva glands which hinders her ability to swallow, talk and eat, requiring further surgery,

She is fearful of him and sought a protection order.

The judge remanded Hausia in custody to be sentenced on February 10, 2022.
