Around the network

The NZECP 34:2001 has set down minimum distances allowed between any new buildings and overhead lines. The minimum safe distances differ depending on the voltage of the overhead lines.

If you need to build close to overhead lines on a private property they may need to be placed underground. EA Networks can do this for you – contact us for advice.

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.

• Request for isolation with at least 48 hours notice during normal working hours. No charge.
• Request for isolation same day service during normal working hours. Normal hourly rate and vehicle charges.
• Request for isolation after normal working hours. Normal after hours rate and vehicle charges.

Step 1: Get reference maps

Contact EA Networks at least two days before you begin work and we will 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 Request and Close Excavation Request to be issued when required.

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 3: 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 EA Networks immediately.

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

Loads between 4.75 and 5.4 metres high:

• We will check the proposed route. If the route is clear to the height required, a permit will be issued. If there are low lines we will arrange to escort the load at no cost.

Loads 5.4 metres high and over:

• We will check the proposed route.
• If the route is clear to the height required, a permit will be issued.
• If the route is not clear we will arrange an escort. A charge will apply.
• If disconnection is necessary, a 15 day notice period is required so we can inform customers who will be affected.

When digging always find out first where network cables and pipes are – get reference maps, or have us mark out the locations for you using our cable location service.

When working near overhead lines make sure that you keep a safe working distance and keep a careful watch when you are operating machinery near lines.

And remember - just because there are overhead lines in the area doesn’t mean there won‘t be underground cables as well.

If you hit an electricity cable or overhead line there is a risk of:

• Electrocution
• Explosion
• Flash over
• Fire

So use our safety services before you start work. Simply contact EA Networks for:

• Reference maps which show the location of our underground electricity cables. Use the reference maps to mark out all pipe locations on the worksite before you break ground, or use;
• On-site advice/mark outs/Close Approach Request for work near strategic electricity, gas and communications cables and pipes.
• Close Approach Request and guidance for work near our network overhead lines and power poles.
• High Load Permit – we will check your route to make sure it’s safe.
