There have been 336 lightning strikes in the South this afternoon and evening, including one that cut power to a Dunedin street and another that hit a house.
MetService forecaster Gerard Bellam said the wider Dunedin area had borne the brunt of the thunderstorms, but there had also been strikes in the Catlins area and off the coast of Oamaru.
The thunderstorms had been caused by a southwesterly front coming through this afternoon and the first cells began forming west of Dunedin about 3.30pm, with the first strikes about 4pm.
By 7.15pm there had been 336 strikes.
A Fire and Emergency New Zealand spokeswoman said firefighters from Dunedin Central were called to what was initially thought to be lightning hitting a house on Glenelg St, Bradford just before 5pm.
