Emergency services were unable to reach the man immediately as the transformer was still live.
A man has died after attempting to retrieve copper from a power box in Christchurch’s red zone.
Power had to be cut to the transformer and about 700 homes before first aid could be provided.
The man was unable to be revived.
“While our inquiries are ongoing, this is a reminder of the dangers of power infrastructure and why it should never be interfered with,” Todd said.
“Anyone who sees suspicious activity around power infrastructure should call police immediately on 111.”
Brooker Ave in Burwood is part of Christchurch’s red zone.
“This was a traumatic incident and we’re making sure the officers who responded have support.”
The man’s death has been referred to the Coroner.
