Power outages

Firstly, you need to register directly with your retailer — for example, Contact, Mercury, Genesis, etc. They hold your account information and pass that to us as the lines company.

We strongly encourage all medically dependent customers to have a backup plan in place and ensure your support network — such as family, neighbours, or carers — are aware of what to do in an outage.
If you don’t have a plan, we recommend speaking to your healthcare provider as soon as possible.
More information about what to do if you, or someone you know, relies on electricity as a medically dependent customer is available online at www.eranz.org.nz.

My power’s out but I’m not part of the outage area shown on the new map?

• The outage area shown on the map is an approximation only.
• If your power is out but your property is excluded from an outage very near your property, please report the outage via the Outage Centre.
• Please also send your name and address to our call centre at info@vector.co.nz and we will investigate.

It depends on the severity of the event, but Vector tries to keep the outage in each area as short as possible – aiming for no longer than four hours at a time in each location. But this will depend on the level of savings required by Transpower. Vector does this by organising a series of outages, beginning in one location for a set period, then moving to the next and the next, until Transpower says the rolling outages can end. Because demand varies from day-to-day, the time and extent of outages notified to customers will be approximate.

Here are some handy tips to keep you safe during a power outage: 

• Report the outage online or check your address for existing outages and register to receive updates.
• Use a torch instead of candles (a torch is safer). 
• Switch off sensitive electrical equipment, such as your TV, computer and stereo as they can be affected by a power surge when power is restored. 
• Keep the fridge closed so food will last longer while the power is off. A freezer will usually keep food frozen for up to 24 hours without power. 
• Turn appliances off. Make sure elements on your stove, the kettle, and all heaters are turned off. This ensures they don't come back on without you noticing when the power supply is restored. 
• Never use a patio heater, gas heater or bbq indoors  during a power outage.
• Don't touch or use any electrical appliances while barefoot in damp or wet conditions. 
• If you go out, be aware that streetlights and traffic lights may not be working. 
• Don't go near any damaged power lines and electrical equipment - stay at least ten metres away. 
• ​If you are concerned regarding health and safety, please either contact the health professional responsible for your care immediately, or go to the local hospital, or if it is an emergency, call 111.

Our main goal is to work as safely as possible to restore power to the greatest number of customers in the shortest time possible. We prioritise the restoration of power to critical infrastructure such as hospitals, airports, water plants and sewage plants.

We restore power in the following order:
 

1. We prioritise repairs to main lines (high voltage lines), and equipment (substations) that will restore the most power to as many customers as possible at once. 
2. Next, we restore individual transformers and smaller lines (low voltage lines) to individual homes and businesses. Please note that we can’t fix an individual problem until the main lines and equipment are restored. 
   ​

If your power remains off after power is restored to your neighbourhood, there may be an issue with your service line. Call us on 0508 VECTOR (0508 832 867)

After a power outage you may not have hot water. For more information on how hot water is restored, see the FAQ.

In severe storms with widespread damage, it may take us a few days to physically assess damage and restore power. In these cases, separate crews are used manage assessment and repair works. If a Vector truck leaves your neighbourhood before your power is back on, please know that we are not ignoring your problem.  

There are two ways in which you can help prevent outages: keeping your trees trimmed and away from power lines, and checking before you dig on your property.
 

• Keeping trees on your property trimmed and away from power lines

Overgrown trees not only cause outages, they also prevent our crews from repairing equipment quickly and delay the process of restoring power.

Trees on private property are the responsibility of the property or business owner whereas trees on public roads are the responsibility of Auckland Council.

Under the Tree Regulations you are legally required to keep any trees located on your property a prescribed distance from network lines. You can find out more about your obligations as a tree owner here.
 

• Checking before you dig on your property

Underground electricity cables and gas pipes are everywhere. They could be under your lawn or driveway. You could hit an underground electricity cable or gas pipe which could result in injury to you, and loss of service for your neighbours.

Before you dig, request free reference maps which show the approximate location of underground cables and pipes at least two days before you begin work. Call 0800 B4UDIG (0800 248 344) to find out the location of electricity cables or gas pipes under your property.

If you have cables or pipes below, make sure you avoid digging in their location. If you are breaking concrete and need equipment such as a rock breaker or excavator to dig but have established that there are cables or pipes nearby, make sure you get a professional contractor to carry out initial digging work.

The Auckland region has a mix of both overhead and underground power lines. 55% of customers have power lines underground in front of their properties. All new developments in the region have power lines underground as the site works for construction and road building typically provide easy and cost-efficient access to install the lines.

However, some areas have overhead power lines because:

• Undergrounding costs up to 10 times more per kilometre than overhead power lines
• Costs are especially high in areas of Auckland built on hard volcanic rock which is common in central Auckland.
• In rural areas, undergrounding power lines is prohibitively expensive given the lower population numbers per kilometre.
  ​

The cost of undergrounding ultimately ends up with consumers, which is why we still use overhead power lines in some cases. They’re affordable and easy to repair when something goes wrong. We use the technology that’s best for each area so we keep the costs down for our customers.

Wouldn't undergrounding all power lines prevent outages?

Unfortunately, faults still occur on underground electricity cables that result in outages. These can happen when:

• Contractors or DIYers hit underground electricity or gas cables
• Underground cables are more resilient to tree damage but can still be damaged by storms if trees are uprooted.

Underground faults may also take longer to find. A field crew may spend hours digging up sections of a road before identifying where the issue lies.

We have service standards which apply in normal weather conditions on our electricity network. In extreme weather conditions or major adverse events outside our control, the usual service standards do not apply, although every effort is made to restore power as quickly as possible.


Our service standards cover:

• The time we take to restore power
• The number of interruptions you may experience
• The power quality you can expect
   

Our residential service standards are detailed in this brochure. 

Our business and commercial service standards are detailed in this brochure. 

Please call us on 0508 VECTOR (832 867) or email us if you have any questions.

As a residential customer, if you report an outage and the issue is found to be on the lines or equipment that you own, we won't charge you for the call out. We’ll make sure the line is safe and you’ll need to arrange your own repairs at your cost. If you’re one of our commercial customers, your electricity retailer may charge you for the call out.

Bad weather, especially gale-force winds, can cause widespread outages when trees come into contact with power lines. Even when electricity cables are underground, tree roots can cause damage to cables if trees fall.

During a storm, we physically assess the extent of the damage to the network, so we can coordinate our field crews repair work. As a storm progresses, the damage and therefore the restoration focus areas can change.

Our main goal is to work as safely as possible to restore power to the greatest number of customers in the shortest time possible. We prioritise the restoration of power to critical infrastructure such as hospitals, airports, water plants and sewage plants. 

We restore power in the following order:

1. We prioritise repairs to main lines (high voltage lines), and equipment (substations) that will restore the most power to as many customers as possible at once.
2. Next, we restore individual transformers and smaller lines (low voltage lines) to individual homes and businesses. Please note that we can’t fix an individual problem until the main lines and equipment are restored. 

​In severe storms with widespread damage, it may take us a few days to physically assess damage and restore power. In these cases, separate crews are used manage assessment and repair works. If a Vector truck leaves your neighbourhood before your power is back on, please know that we are not ignoring your problem.  

During the first few days after a widespread event, it may be difficult to provide accurate estimates for restoration times to individual properties.

After a power outage you may not have hot water. For more information on how hot water is restored, click here.

Outage categories indicate the typical severity  of an outage and the type of work required to restore power. Minor outages usually involve small, local faults, while moderate and major outages involve increasing levels of damage to power lines, poles, or underground cables. Complex outages are much less common and involve severe damage, extreme weather, or hard‑to‑access locations, which can extend restoration times.

In the absence of severe weather events,

• Minor (up to 4 hours) : 75% of outages are fixed with a simple repair, usually within 4 hours.
• Moderate (up to 8 hours) : Around 10% of outages take up to 8 hours to restore because they need more complicated repairs.
• Major (up to 12 hours) : About 5% of outages take up to 12 hours to fix because they involve complex technical repairs.
• Complex (+12 hours): In rare cases, outages take more than 12 hours to restore due to severe damage or hard-to-reach locations.
  

Most power outages last less than four hours. When our crews get to site they will assess the outage by complexity.  The Outage Centre will report whether an outage is minor, moderate, major or complex and give an estimated time to complete the repair. As the repair progresses, the crews will provide a final restoration time.

This new approach gives customers an earlier understanding of the complexity of the outage and the time it will take to repair.

The Outage Centre will have the latest outage information and will be updated by our crews as new information comes to hand. If for any reason, you are still without power after an outage has been reported as resolved, please call us on 0508 VECTOR.
