Workers installing ultra-fast broadband fibre optics in Rotorua's central city accidentally chopped through a gas pipeline.
The incident, which happened about 4am yesterday, cut the gas supply to about 20 properties.
Vector communications manager Sandy Hodge said the contractors, who don't work for Vector, identified where the main gas lines were but failed to mark them before a digger cut through the mains.
Vector staff were there within an hour to temporarily repair the line and reinstate the gas supply.
The cabling is part of a city-wide project to install an ultra-fast broadband network in the central business district.
