If you are planning on doing any digging on your property – including building a fence, landscaping or major gardening, concreting, excavation, putting in a pool, or construction – you should check the location of any underground cables before you start.
The beforeUdig service is the first point of call for any individual or contractor requiring information on underground pipes and cables in New Zealand. By using this service, you can obtain plans from a number of asset owners, including Wellington Electricity, simply by making one enquiry.
Get reference maps
Call beforeUdig on 0800 248 288 or visit www.beforeudig.co.nz to request maps indicating the approximate location of underground services. It will take at least two working days to process your request, so plan ahead to avoid risk.
Mark out the service locations
Use the reference maps as a guide for locating and marking out all cables and pipes within your worksite. We remind you of your responsibilities under the Health and Safety at Work Act 2015, whereby you must establish the location of underground services before commencing excavation.
Wellington Electricity does not provide the services required to identify and mark out any underground cabling or wires near the site you are proposing to dig. You are responsible for confirming the location of our underground cabling and wires within your worksite before you start work. You will need to engage a third party contractor to provide you with mark out services (at your cost). Please note that the following contractors may be able to provide you with these mark out services:
- Cable Locators | 0508 562 283 / www.cablelocators.co.nz
- LoKate Services Ltd | 04 566 4002 / www.lokate.co.nz
- Reveal Infrastructure Ltd | 0800 240 340 / www.reveal.nz
- Underground Service Locators | 0800 425 622 / www.undergroundlocators.co.nz
Other service providers can be found in the Yellow Pages or online by searching for ‘underground service locators’.
Wellington Electricity will, where available, provide you and/or your contractor with reference maps and plans. Wellington Electricity and its related companies take no responsibility for the provision of the mark out services and are not liable to you or your contractor should anything go wrong in the performance of the mark out services (whether an issue arises from the reference maps and plans provided by Wellington Electricity or otherwise). The accuracy and completeness of Wellington Electricity’s reference maps and plans cannot be guaranteed and Wellington Electricity and its related companies do not accept any responsibility, arising in any way, for any errors or omissions from any reference maps and plans provided by Wellington Electricity, or for any lack of accuracy or completeness of them.
Please also note the following additional advice contained in WorkSafe's Guide for Safety with Underground Services – “In conjunction with location devices and plans, trial holes by careful hand excavation are essential before any excavation is commenced. Hand digging must continue until all of the services have been found. If there is any doubt as to where the service is located, stop work and consult with the service owner.”
Do not dig within five metres of one of our power poles without a Close Approach Consent. Depending on the depth of excavations, you may need additional pole supports to prevent poles collapsing. We can advise you and will provide supervision in some cases. You can find more information on this by clicking the button below.
