About 150 electricity customers were without power in Mataura, Southland early today after a milk tanker hit a power pole around 3am.
Between 12,000 and 15,000 litres of milk spilled into a drain which led directly to the Mataura River, Environment Southland said.
Fortunately, from an environmental perspective, the lower reaches of the river were in flood overnight, so the milk would have been diluted immediately and was unlikely to have any lasting environmental impact.
Network company PowerNet said the crash had a significant impact on the area's power supply as the pole was in a key position. All affected customers had power back on by about 11.30am.
At the same time as the crash, power went off in a second area and around 7am efforts were still under way to find the cause of that problem.
Police said the driver was unhurt in the crash, which caused power lines to come down. Some milk had been transferred to another tanker.
