Yesterday about 300 households were without power in Clarks Junction, Hindon, Redbank, Ranfurly, Waipiata-Kyeburn and Middlemarch-Bald Hill, PowerNet said in a social media update.
The company said it had found more than 30 broken poles and more than 20 broken cross-arms.
Crews from Invercargill, Gore, Balclutha, Palmerston and Ranfurly were able to restore electricity to about 100 customers on Monday, however some people may be facing another night without electricity tonight, the company said in a statement this morning.
"Crews will be working to restore power to as many people as possible today, and a generator is on its way to the area with the hopes that power can be supplied to many of those impacted while repairs are undertaken.
"Aerial surveys of the lines were undertaken yesterday, which revealed around 30 poles were impacted by the heavy snow on the 33kv line between Clarks Junction and Hindon."
Those currently without electricity include customers in the Clarks Junction, Hindon, Ranfurly-Kyeburn Diggings, Middlemarch-Bald Hill and Merton-Hummock areas.
PowerNet said the safety of crews was a priority, as conditions remained treacherous.
It would continue to provide updates via its website and Facebook page.
Customers who have not previously reported their power is out should do so now by phoning 0800 808 587.
NZ Transport Agency urged caution on roads across the South Island as more snow, heavy rain or ice could make for dangerous driving conditions.
