The couple had been together for about 18 months. They last spoke on Sunday morning. Bourton tried calling his wife about 10 minutes before the crash while he was in Southland.
Following the crash, he got a call from a police officer who said his wife had died in the crash.
Bourton said his son, who was sitting in his car seat, is okay, with just a couple of bruises. “Not a scratch on him,” he said.
Bourton said his wife would be sorely missed, and said the journey ahead without her would be incredibly difficult.
“Tough roads lead to beautiful destinations.”
He wanted to thank police and the staff at the hospital for all their help.
“They’ve just been fantastic ... just unbelievably good people.”
He offered his condolences to the family of the other driver.
Family members and friends of the two have shared tributes on social media.
A friend of Bryan Kerr, Corey Rogers posted online: “With a heavy heart, I’m so sorry to say Bryan Kerr has passed away in a car crash in [Leithfield] yesterday coming home from fishing in Kaikōura.”
Bryan Kerr was a member of the Canterbury Jet Sports Club.
The club posted online: “We send our condolences. B.K. was a great character to have in the club and we will miss him dearly.”
Another friend said on social media: “Such a relaxed and genuine guy who always loved a good laugh. I have great memories of us hanging out at the Marine and parties in Sumner.”
Senior Sergeant Stephen McDaniel earlier told the Herald the cause of the crash was yet to be determined.
McDaniel said motorists needed to “drive to the conditions and be aware of your capabilities and tiredness”.
“When it comes to road safety, it’s all about people driving to the conditions. It’s about fatigue, it’s about pulling over and stopping. The number of causes of accidents, a lot of it is fatigue or it is a distraction and speed as well.”
It’s now the deadliest start to the year on the roads in recent years, with 35 people killed in crashes from January 1-30, according to Ministry of Transport data.
The toll is more than double the amount (17) killed in the same period in 2021.
Police’s Canterbury prevention manager, Inspector Ash Tabb, told the Herald any road deaths are “devastating” and are “felt by many”.
“Many of the crashes emergency services respond to are preventable. We see too many crashes where motorists have chosen to speed, drink drive, be impatient or let themselves get distracted and take their eyes off of the road,” Tabb said.
“Deaths on our roads not only impact the family and friends of those involved but the emergency services who respond and the public who witness the crash.”
