One person has died and another is fighting for their life following a horrific head-on crash in West Auckland on Wednesday afternoon.
It was the fourth death in as many crashes on New Zealand roads yesterday.
The two-car, head-on crash occurred near Waimauku, north of McPike Rd, about 5.15pm, forcing the closure of State Highway 16 between the Waimauku roundabout and Kiwitahi Rd.
Photos from the scene show the mangled wreck of a car that appears to have taken the full force of the collision. Emergency workers attended to the injured.
A police spokesperson said three people were flown to Auckland Hospital after the crash.
Two were in a critical condition and the third in a moderate condition. One of those in a critical condition had since died, the spokesperson said.
Earlier on Wednesday evening, the Auckland Rescue Helicopter Trust said it flew a 20-year-old woman with multiple injuries to Auckland City Hospital.
On Wednesday morning one person died following a serious crash near Wellington's Terrace Tunnel during the morning commute.
The crash closed the tunnel, stopping traffic heading in both directions and did not re-open until just before 12.30pm.
Meanwhile, a serious crash near Pūkaki, South Canterbury, resulted in the death of one person and two more were seriously hurt.
A police spokesperson confirmed one victim had died in the three-car crash just after 3pm on Wednesday.
The crash took place at the intersection with Mount Cook Rd and Tekapo-Twizel Rd near Pūkaki.
Police said two others were seriously injured and a third person had moderate injuries. Fire and police crews also attended the crash.
State Highway 8 was closed for a period at Lake Pūkaki.
And another person died after a single-vehicle crash on the East Coast.
Police say the crash happened shortly before 1pm on SH35 south of Tologa Bay.
A second person in the vehicle was taken to hospital for injuries not thought to be serious.
