The Electricity Authority says Northlanders deserve answers - as it launches an investigation into a toppled electricity tower.  

The region experienced outages yesterday after a transmission tower fell down northwest of Auckland. 

Transpower says its workers were carrying out maintenance at the time and has started an investigation. 

Senior Political Correspondent Barry Soper told Heather du Plessis-Allan “It knocked out power to 100,000 users.”  

Soper said “Simeon Brown was there today – he said the event was completely unacceptable.”
