Transpower has partially restored power to areas in the top part of the South Island and the West Coast after severe weather caused faults on Transpower’s network earlier this morning.

Greymouth, Stoke, Blenheim, Culverden and Kaikoura have been reconnected to the national electricity grid, and local lines companies in those areas are in the process of supplying power in their respective networks.  

While the severe weather event continues, further outages are possible. We will continue to work hard to restore power while keeping our crews safe.

More details will be provided on Transpower’s website and Facebook page. People can also check the websites of their retailers and local lines companies for up-to-date outage information.
