* A power pole is blocking a residential street in Titahi Bay after being knocked over by a street sweeper.
Mawhare St resident Matt Duncan said the vehicle hit the power about 11am. A fire crew have arrived and Wellington Electricity staff are also assessing the situation.
''The pole is lying over the road. No power has be disconnected yet, but it will have to be so they can fix it,'' said Mr Duncan
He said because the pole was blocking the road and power lines were strewn about residents were unable leave the street.
''At this point I'm negotiating with the power the guys, but there are lines all over the road. They think some of them might be phone lines.''
Wellington Electricity spokesman Geoff Thornburn confirmed the power pole was one of their's and a saff member was on site assessing the situation.
He said 12 customers had had their power turned off.
"They have been isolated for safety reasons and they will be off about four hours while the pole is replaced.''The power pole was a low voltage one that was not part of the backbone of the network, he said.
