Togiai, 33, was a Samoan-Kiwi brought up in South Auckland.
According to a report by The Melbourne Age, two Melbourne-based men - Abdullah El Nasher and Mikhael Myko - were arrested by NSW Police in Sydney shortly before 10pm last night.
The Age reported a "dramatic" arrest scene when police arrived a Bankstown apartment block where the two men had been hiding out.
The two arrests followed a week-long manhunt for those believed to be involved in the shooting.

"Abdullah El Nasher jumped from a balcony to a lower floor in an attempt to escape police and was treated by NSW Ambulance paramedics before being taken to Liverpool Hospital," the report read.
"On release, he will be charged with a Victorian arrest warrant for murder."
Myko, his associate, was arrested on the spot and taken to Bankstown Police Station. There, he was charged with a Victorian arrest warrant for murder.
Both men were expected to appear at Parramatta Bail Court on Saturday.
Dramatic dashcam footage from the night Togiai was killed shows the shooting spree, which left two others fighting for their lives.
The group were ambushed as they left the boxing event at Melbourne Pavilion, in Kensington, about 10pm.
The footage shows a man with a satchel slung over his shoulder running towards a confrontation unfolding across the street, just outside the pavilion's front door.
The father of a 3-year-old daughter, was shot in the side of the chest and died at the scene.
Two other men, a 34-year-old from Lalor and a 32-year-old from Craigieburn, were both taken to hospital with gunshot wounds.
Togiai's family and friends have taken to social media to pay tribute.
His wife, Shae Mccoullough, said she'd give anything to bring him back.
"How am I supposed to say good bye? How do I tell my little girl that daddy's not coming home?" she wrote.
"I'm so heartbroken and can't even begin to imagine how hard life is going to be without you!"
Mccoullough described how Togiai would no longer get to see their daughter, Alyssa, "grow, or see her on her first day of school, you won't be at any birthday parties or even get to walk her down the aisle".
Mccoullough said Togiai was a "one of a kind and an awesome dad".
Togiai grew up in Ōtāhuhu and went to Fairburn Primary and Ōtāhuhu Intermediate schools.
He moved to Melbourne as a young teenager, and more recently lived in Craigieburn, and worked in construction.
