Two people have died following two separate serious crashes on State Highway 1 south of Levin this evening.
One person died following a serious crash on SH1 near Mcleavy Rd around 4.50pm, a police spokesperson said.
Two other people were injured in the crash and were transported to hospital by helicopter, one with critical injuries.
"Diversions are in place but motorists should expect significant delays and avoid the area if possible," the spokesperson said.
Motorists are asked by the NZ Transport Agency to follow directions of emergency services on the scene and allow extra time.
About 7km south of the first incident, another person died in a seperate crash, around 7.10pm.
The second incident involved a car and a truck and occurred north of the intersection of Waikawa Beach Rd and SH1.
Both crashes forced emergency services to close SH1 and detours were put in place.
