About 22,000 Powerco customers in Tauranga lost supply for 30 minutes this morning after a fault on the national grid.

Network Operations manager Phil Marsh says the fault affected Powerco's Omanu, Papamoa, Matapihi, Te Maunga and Triton substations.

'Supply was lost at 7.43am but Powerco and Transpower worked together to restore power to all affected customers over the next half hour.
'National grid operator Transpower is investigating the cause.”
