He was named by police this morning as Constable Matthew Dennis Hunt, aged 28 of Auckland.
A 24-year-old man will appear in court in Auckland today charged with his murder.
Constable Hunt started with police as a member of Wing 312 in October 2017.
He spent the majority of his career working frontline at Orewa and Helensville Stations before recently moving to work in the Waitemata Road Policing Team based at Harbour Bridge Station.
Hunt was raised on the Hibiscus Coast by his mother Diane, with his sister Eleanor.
He attended Orewa College.
"It was his life-long dream to be a police officer," his family said in a statement.
Before joining the police, he completed a BA in criminology and worked at Auckland Prison as a case manager.
He also spent time living in the United Kingdom before he returned to New Zealand to join police.
"Matthew was a person of great integrity," his family said.
"His closest friends were like his brothers and sisters and they along with his family are absolutely heartbroken by what has happened.
"He was passionate about sport and his physical fitness and was thrilled to enjoy the recent Blues game at Eden Park with his mates."
Police added: "Our priority remains on supporting his family at this tragic time."
They were also looking after the welfare of other police staff who attended the incident, including the other injured officer, as well as the injured member of the public.
Routine traffic stop followed by shooting
Yesterday, Hunt and another officer had chanced upon a car that was flagged as being of interest, connected to potential criminal activity.
The officers turned on their lights, sirens and signalled for the car to pull over at 10.28am but soon lost sight of the car.
They then found it crashed on Reynella Drive, off Triangle Rd, one of the main arterial routes in Massey. There were two people in the vehicle.
The situation escalated quickly, if not immediately, Police Commissioner Andrew Coster later said.
A man got out, armed with a long-barrelled firearm and fired repeatedly.
Hunt was fatally shot while the other was wounded.
The man then got into a silver Mazda Demio nearby — with a second person — and they took off.
At some point in the day one of the fleeing cars struck a member of the public, injuring them.
A police manhunt fanned out across the region, closing streets.
At 1.45pm, Coster was tasked with delivering the news of the first police officer killed on the front line in 11 years.
In Wellington, he booked a flight to Auckland to offer his support.
By 5.30pm, he was at the Henderson police station telling media they had two people in custody and had recovered a firearm.
Officers across Auckland would remain armed until Coster was confident the "right people are in custody".
"Our priority is to hold this offender to account," Coster told media.
"I ask that you keep this officer's family in your thoughts, as their loved one will not be coming home tonight."
