Police said the Serious Crash Unit carried out a scene examination and inquiries into the cause are ongoing.
Senior Sergeant Christine Pinfold from the Central District Command Centre said police would like to hear from anyone who captured CCTV prior to the crash.
“We believe the vehicles were travelling south on Tremaine Ave, towards Malden Street when the crash occurred.
“We ask that people with CCTV in the area please review it and contact us if they have video showing two vehicles travelling down the avenue just before 2.30am.”
The fire service was called around 2.25am, Fire and Emergency central shift manager Jill Webley said.
One car was on fire and was extinguished, Webley said.
A Hato Hone St John spokesperson said it was notified of the incident at 2.27am, with two passengers taken to Palmerston North Hospital.
“Three ambulances, one rapid response unit and one operations manager attended.
“Two patients, one in serious condition and one in moderate condition, were transported to Palmerston North Hospital. One additional patient, in moderate condition, was assessed and treated at the scene and no transport [was] required.”
It follows a deadly weekend on New Zealand’s roads, with six people dead in six separate crashes over 24 hours, while two more people were killed in a two-truck crash near Levin yesterday.
As of midnight, 77 people had died on our roads this year, up from 73 this time last year.
