Powerco in conjunction with sub-contractors Bruce Buchanan Ltd initially put in 800m of underground cabling from Jellicoe St south at a cost of $153,000, and telephone cables were laid in the same trench.
Greytown Community Board was quick to take hold of the opportunity to maximise the effect of the underground power supply by voting to scrap the concrete power poles for the heritage lights.

He has been acting chief executive since the departure of Dr Jack Dowds and confirmed yesterday he intends to apply for the full-time position.
