In Auckland, an electricity cable upgrade project to improve the quality and reliability of power supplied to Middlemore Hospital is underway.
The work will be carried out by using Trenchless Technology methods predominantly.
The work will take place in small sections along the route to minimise disruption, by energy infrastructure company Vector.
Full traffic management plans have been developed and will be used throughout the project work, and the work sites have been designed so that pedestrians will still be able to pass by the works.
The project is expected to be complete in October 2012.
