A family suffered two deaths in a fatal two-vehicle crash near Christchurch earlier this week.

Emergency services were called to the crash on Main North Rd in Sefton at about 10am on Monday. Police said two people had died, while three others were injured.

A Givealittle page set up for the affected family has revealed Michael Wong, 39, and his visiting mother were killed in the crash.

Three family members were also injured.

Proceeds from the fundraiser will go towards supporting the family, including Wong’s wife, with funeral costs among other expenses.

“It is the worst nightmare for a loving mother and wife who always striving hard daily for her family.”

NZ Transport Agency Waka Kotahi has said safety improvements are planned to reduce crashes on the stretch of SH1 where the crash occurred, including widening the road and installing median barriers.

The agency said on the project website that the 11.4km stretch of SH1 between Saltwater Creek and the Cam River has been assessed as a high-risk section of highway, with high traffic volumes and speeds combining in some areas.

Five people were killed and 30 seriously injured in the 75 recorded crashes on the stretch of road between 2011 and 2020, many caused by head-on crashes.

Waka Kotahi said it can’t “remove every hazard [but] we can put in place effective measures that will make SH1 in North Canterbury safer for everyone who uses the road”.

Waimakariri District Mayor Dan Gordon said earlier this week the crash was devastating.

“A death on our roads at any time of year is devastating, but that feeling of loss is potentially even greater as many of us are still in the holiday season,” he said

“My thoughts and deepest sympathies are with the families and friends of those who died in the road accident in Sefton this morning.

Gordon also acknowledged the dedicated work of the emergency services personnel in our district “who attended this tragic scene”.

“Please take extra care out there.”
