A notoriously dangerous stretch of highway running through Horowhenua is the scene of yet another car crash.
Two vehicles collided in a head-on crash shortly before 4.30pm on SH1 near Taylor's Rd, north of Ōtaki.
A police spokesperson said two people had been injured, although their condition was still unknown.
Traffic backed up at a standstill in both directions, before a diversion was established around South Manakau Rd for southbound traffic.
Northbound traffic was still moving very slowly.
