A power pylon is just twisted metal after being torn down by the effects of the nearby flooded Rangitata River.

​Nine Transpower pylons crossing the Rangitata River in South Canterbury have been damaged by flooding.

The State-owned national power grid owner said all the towers were on one transmission line and it is not live.

"One of the towers has been swept away by the flood waters, two are on the ground and a further six are standing but have varying degrees of damage," spokesperson said.

"There has been no loss of power to communities as a result of the damage, with Christchurch and the upper South Island currently being supplied by other transmission circuits.

The spokesperson said Transpower does not anticipate there will be any issue with the supply of electricity, unless the situation changes.

JOHN BISSET/STUFF Rangitata, about 45km north of Timaru, was put into a state of emergency in December 2019 as the Rangitata River burst its banks following significant rainfall that led to widespread flooding and slips, considered a one in 20 year event.

Transpower's primary objective today is to ensure the areas around the towers and line is safe, so that further assessment can take place and we can begin to plan the repairs.
