The main road between Wairoa and Gisborne was closed for four hours Friday after two light trucks collided just north of Morere Hot Springs.
Fire and Emergency NZ reported two "small trucks" had collided about 8.30am on State Highway 2 near the intersection with Tunanui Rd, almost 50km northwest by road from Wairoa.
No one was reported to have been trapped in either vehicle but crews from the Wairoa and Nuhaka volunteer brigades had prepared a site for a rescue helicopter and was thought two people had received moderate to serious injuries.
The rescue crews were understood to have left the scene by 10.45am but two tow trucks were still clearing the vehicles from the road, which did not reopen until about 12.30pm.
State highways management agency Waka Kotahi NZTA said had there was no suitable detour during the emergency.
