The Chase is a four-day Herald series looking at police pursuits and fleeing drivers. Since January 2008 there have been more than 30,000 pursuits, hundreds of crashes and 79 deaths. The series runs from Monday to Thursday ahead of a joint review of pursuits by police and the IPCA which will be released on Friday.
When a police pursuit turns fatal we often hear from the families of the dead - the offending drivers, the innocent passengers, the other road users caught up in the carnage.
But we rarely, if ever, hear from the police behind the wheel in those pursuits; the officers who make the call to chase fleeing drivers in the first place.
Today, two officers have agreed to speak about their experience to give an insight into the police side of fatal pursuits.
Both officers spoke to the Herald as part of The Chase, a four-day series looking at police pursuits in New Zealand, on the condition they were not named and the crashes they were involved in were not identified out of respect to the families of the dead.
'It wasn't my fault - I was just doing my job'
Officer B still chokes up when he talks about his first fatal pursuit.
Like Officer A, he is a long-time cop and pursuits are part and parcel of the job - but his first fatal is one he cannot forget.
The pursuit began after he came across a motorcyclist riding at a dangerously high speed - at least 155km/h in a 100km zone.
"But then his riding started to deteriorate, he started moving onto the other side of the road - he wasn't driving into oncoming traffic, but his riding started getting worse.
"I thought 'this is a stupidly high speed and if he flies off he's really going to hurt himself', I thought 'this is going to go really, really bad'."
The rider was heading to a 50km zone at 190km/h and Officer B decided to abandon the pursuit.
"I thought 'this is ridiculous, I'm abandoning' and I pulled over.
The pursuit lasted 2.5 minutes and covered more than 12km because of the high speed.
Officer B watched the rider "vanish" into the town.
About 1km from where he had abandoned the pursuit, the rider had run through a major intersection at speed - later found by the Serious Crash Unit to be 120km/h - and collided with another vehicle.
"The first thing that goes through your mind is 'oh s**t'," he explained.
"It was absolute carnage … I watched CCTV footage of it later on and he didn't even try to brake, he just went straight through the intersection and hit another vehicle."
Officer B couldn't immediately see the rider but could see a fire crew down the road.
He went to speak to the driver in the other car who was - miraculously - uninjured.
"I asked where the motorcyclist had gone and someone said 'he's down there' and I realised the fire crew was working on him," Officer B said.
"I walked up and looked at him and I just said "oh my God' ... he wasn't moving, he had severe injuries… I thought 'Jesus Christ this is my fault, this is my fault, this is really bad," he said.
Other police arrived at the scene and took over.
Officer B 's immediate boss called him and told him to go home.
He explained what would happen next and said he would contact him again later with more information.
The rider was taken away an in an ambulance and Officer B went home.
He said pursuits were "not fun" - they were the total opposite.
"These fatal pursuits don't just affect me and the person involved, they affect our families and so many other people and the effects are just so long-lasting," he said.
""I'm not only a police officer I'm a father, a husband, son, brother - I get affected by these traumatic events the same as everybody else.
"Just pull over, nothing is worth losing your life over or killing an innocent member of the public because you're stupid enough not to stop."
Officer B said there was a misconception by some people that if they drove really fast police had to abandon a pursuit.
It was Officer B 's first fatal pursuit, and while he hopes it will be his last, the reality is he could be in the same position any time he goes to work.
"No one wants a pursuit," he said.
"If people would just pull over, take responsibility for their actions, we wouldn't have to.
"Don't put yourself at risk, don't put anyone else at risk, just pull over - don't be stupid."
Officer's warning ignored 48 hours before tragedy
"You guys are going to end up crashing and killing someone," said Officer A.
"Nah mate," replied the driver of the stolen car, stopped for joyriding minutes earlier.
"I could see silhouettes through the tinted windows so I knew there were a few people in the car."
"They got up to 140 to 160km/h… there wasn't much traffic on the road, we maybe passed 10 cars in a 1km stretch but they were all getting out of the way."
As the driver turned corners he crossed the centreline - but one deceptively tight corner was his undoing.
"He stuffed it up … he hit the brakes but the car left the road and went up a bank," Officer A recalled.
"It spun 360 degrees in the air, it was like an action movie, then it came down in the middle of the road."
The driver tried to flee on foot but Officer A and his colleague were too quick.
"How close do you have to come to death? There is no value put on their lives."
Officer A has seen it all when it comes to pursuits.
He's seen drivers leap out of mangled wrecks and take off on foot, only to be tracked and caught by police dogs.
He's been rammed by much bigger vehicles as they try to get around police blockades.
Nothing really surprises him any more - but his dream result would be never partaking in another pursuit for the rest of his career.
"I've seen a few (pursuit-related crashes) in my career - once a car doing 200km/h clipped a barrier and spun up an onramp like it was in a pinball machine and the offender got out and ran away.
A week later Officer A spoke to the offender who said: "I was driving recklessly because you didn't abandon the pursuit."
"I was driving so fast, why didn't you abandon? I can't believe you did that officer."
"I couldn't get into this guy's head that he was the dangerous one," Officer A said.
"The escalation in their minds is 'if I drive like a dickhead then the police are going to pull out and if they don't pull out I'll drive worse and worse'.
"That's scary - they're thinking 'I'm going to drive more and more dangerously until the police leave me alone'."
Officer A said drivers under 17 were involved in more than half of the pursuits he had been in.
Afterwards he had to give a "ginormous" statement to his colleagues about what had happened - every movement and action scrutinised by his managers and then the Independent Police Conduct Authority.
He vividly remembers walking into the station to give that statement.
"No one would talk to me, I had to have a lawyer with me - I felt like I was a suspect in a crime," he said.
"I felt like I was the bad guy, that was a horrible feeling.
"But I knew I'd followed policy.
"The most frustrating thing is we get scrutinised probably more than the offender who is the person who chose to run in the first place and drove dangerously.
