Safe Digging

When digging always find out first where network cables and pipes are - get reference maps, or have us mark out the locations for you.

Step 1: Get reference maps

Call us at least two days before you begin work on (09) 430 1803, and we’ll provide free up-to-date reference maps showing underground cable locations. We may be able to provide these maps in less than two days to meet an urgent request, but a charge will apply.

We will contact you if any strategic network cables or pipes are shown on the maps you have requested, advise whether onsite advice will be provided and for the appropriate Close Approach Consent to be issued.

Step 2: Mark out the service locations

Use the reference maps to mark out the location of all cables on the worksite before you break ground. Maps are a guide only. Use an electronic cable or pipe locator whenever possible.

Step three: Hand dig to expose cables and pipes.

Why hand dig? Hand digging is less likely to cause serious damage to cables and pipes. You must dig with caution for your own safety. Any damage to a cable or pipe should be reported to Northpower immediately - call (09) 430 1803.

AND remember to watch out for services coming off a main.

Cable and pipe depths

Our cables and pipes are laid at different depths in the ground, varying from 600mm to over 1200mm. Alterations to the ground cover may reduce or increase the depths. We cannot guarantee the depth of any cable. Expect a cable or pipe to be at any depth and don’t rely on finding buried marker tape when you dig as this may have shifted over time.
