Police were called about 1.50pm to an accident involving a car and trailer crashing into a power pole on State Highway 1 and Dowling Road near Woddlands causing power outages in the surrounding area.
A St John spokeswoman said two patients one with minor and one with moderate injuries were taken to Southland hospital.
Powernet crews were almost finished installing a new power pole at 6:15pm and salvage trucks were still removing the car and trailer.
The highway is open but drivers are asked to take care.
